ownCloud Client does the rest.
.

@marcorighi You could follow https://doc.owncloud.org/desktop/2.0/troubleshooting.html#core-dumps to get a core dump which could help debugging this.

...or even start the client with:

gdb owncloud
r --logfile -
thread apply all bt

Hi,
I have not check if debug file contains "security-data". If yes, please,
inform me and I will change the passwords.

I have used "tee" because using your instruction set I did not get a
debug file.

So I used the follwing instructions and the debug file is attached.

(1) gdb owncloud | tee ocdebug.txt

after that gdb is started

(2) r --logfile -

after segmentation fault

(3) thread apply all bt

Let me see please.

Best,
Marco

@marcorighi If you attach it in the e-mail we cannot see it. You have to paste it in the webinterface here..
If you just show the bt output it should be OK, no security relevant data.

@guruz Those instructions could be useful as an addition to the docs about core dumps :-)

guruz · 2015-11-09T21:49:38Z

@marcorighi And which of those threads crashed? Thread 1? The output should mention that too?
Also a few log lines before might be nice (feel free to obsfuscate filenames)

@RealRancor As usual you are right. :-|

marcorighi · 2015-11-09T23:39:00Z

The crash is after a random time. Now it is not crashing...

You can find the complete debug here.

@marcorighi Which exact distro is that btw?

guruz · 2015-11-10T11:37:13Z

@ogoffart @dragotin The GETFileJob is getting a readyRead() after the sync had been ended?

marcorighi · 2015-11-10T11:46:14Z

I use Ubuntu 14.04 LTS.
