Slack crashes on upload

[memberbetty]

Issue description

Slack crashes when trying to open the window that one can use to upload a file.

/run/current-system/sw/bin/slack
(electron) 'app.makeSingleInstance(cb)' is deprecated. Use 'app.requestSingleInstanceLock() and app.on('second-instance', cb)' instead.
Creating Slack Application
Cannot upload crash dump: cannot exec /usr/bin/wget
Failed to get crash dump id.
Report Id:
Segmentation fault

Steps to reproduce

Press the '+'-button and select 'Your computer' in a chat.

Technical details

This happens with the master version of Slack that was updated a few days ago.

slack[14978]: segfault at 0 ip 00007f553a42a9fd sp 00007ffd5424ea18 error 6 in libc-2.27.so[7f553a2fa000+13d000]

I cannot seem to reproduce this, but possibly that's because of some other impurity that's present. I'll keep trying.

[memberbetty]

My host operating system is still 18.09, so I referred to this master version as:
environment.systemPackages = [checkout_of_master.slack]

Perhaps that helps?

[dtzWill]

Works here? Just uploaded file in chat with myself xD. Not sure why that would be happening... maybe it needs some gtk bits in profile/env that I happen to have but you don't? :/

GTK impurity sounds like a likely suspect indeed.

I lost the ability to reproduce #54278, but from a cursory look at strace -fo slack.strace result/bin/slack from master, I'm pretty sure it would be it.

I am having the same problem. I was finally able to isolate the issue. It occurs for me if the directory contains a gif.

To reproduce,

• Download gif to directory, e.g. fast parrot
• Click paper clip -> Add file from your computer
• Navigate to directories without gif --> ok
• Navigate to directory with gif --> slack crashes

I have slack for ubuntu 18.04 e0514fa-s@1586890343

[jakewc]

Same problem as the above here - only seems to happen for directories containing gifs.

Uninstalling and reinstalling slack fixed this problem for me (nix-env --uninstall slack; nix-env -iA nixpkgs.slack).

It looks like slack was looking for some things in the wrong place:

I suffered from the same issue. It happened to me twice and each time I tackled it differently.

Note: I'm using GNU/Linux Ubuntu 18.04, slack installed by snap.

First time, it was because of navigating to a directory with a gif file, as mentioned by the folks here. If this is the case, you can solve this by editing ~/.config/Slack/Preferences. You will find there the path containing the gif file. Change the path to anywhere not containing the git file. Save the file, restart slack. It should work just fine now.

Second time, it wasn't because of a gif file. It just happened that I opened slack one day and the upload file window will cause slack to crash. I stopped slack, removed the cache directory: ~/snap/slack/common/.cache, and launched slack again. Everything is back to normal.

[medienlampe]

I stopped slack, removed the cache directory: ~/snap/slack/common/.cache, and launched slack again. Everything is back to normal.

I encountered this issue today, too.
Also with Slack installed as Snap (v4.19.2) on an Ubuntu 20.04 LTS.

@ahmad-elkomey: Deleting the cache directory did the trick for me. Thanks for sharing!

@ahmad-elkomey: Deleting the cache directory did the trick for me. Thanks for sharing!

It did the trick for me too! 👍

[7hibault]

I got the same issue and deleting the cache did the trick for me as well !

Snap 4.19.2 64-bit
Ubuntu 20.04.3 LTS

[MariaKokshaikina]

I faced this issue all of a sudden today too. Thanks, @ahmad-elkomey. Your solution with deleting the cache directory worked for me too

[luizsgpetri2]

Deleting the cache files did the trick as described on #58273 (comment)

[IsmiKin]

Deleting the cache as @ahmad-elkomey said didn't work for me, however, doing it through the app it worked, thank you for the tip! 😄

Help -> Troubleshooting -> Clear Cache and Restart

Ubuntu 18.04.5 LTS

[sobi3ch]

Same problem here

Snap 4.19.2 64-bit
Ubuntu 20.04.3 LTS

..and same solution works like a charm

I stopped slack, removed the cache directory: ~/snap/slack/common/.cache, and launched slack again. Everything is back to normal.

Thanks @ahmad-elkomey

@ahmad-elkomey
TRIPPLE Thanks for the cache clean idea !! works like charm

[ganesan-prenetics]

Had the same problem. Deleting the cache directory didn't work.
This solved it for me.
Attach file (chat with yourself ) --> View all your files --> Upload a file --> change directory (where there are no gifs) and upload something.
Next time 'Attach File' works normal

[serhii-zasulskyi]

Thanks @ahmad-elkomey , cache cleaning solved the issue

[bledi1985]

for me too

[zdhamasha]

same issue here

[joshuafishman]

Cache clearing doesn't work for me, but uninstall/reinstall through snap does.

[Aubreymcfato]

Cache clearing doesn't work for me, neither uninstall/reinstall through snap does. :(
Do I have to manually remove the ~/snap/slack/common/.cache folder?

EDIT: removing manually the folder, it worked.

Hey, thanks for the report as this is stale for longer time and I confirmed its working on stable and unstable.

[Systho]

I still had the issue today.
clearing the cache from the menu did not work, deleting the cache manually with slack closed worked.
I'm on 4.36.140

[SebTM]

Can't reproduce on latest unstable with 138, where did you got 140? Is it beta? If I try to download latest release from slack I get 138-0.1 still

[Systho]

I might be on beta indeed. To be honest I'm not sure since I installed a while back and just keep the auto updates
