[Arch] Steam crashes on startup; Steamwebhelper is not responding

[adoa]

Your system information

• steam 1.0.0.78-2 as packaged by Arch Linux
• Arch Linux
• Gnome + Wayland
• Opted into Steam client beta?: No
• Have you checked for system updates?: Yes
• Steam Logs: steam-logs.tar.gz
• minidump: minidump.zip
• GPU: AMD RX 6700 XT with mesa 1:24.0.1-1 as packaged by Arch Linux
• Be aware! I have a symlink in place /home/valneq/.local/share -> /data/valneq/local/share
• My primary library is at /games/valneq/steam/library

Please describe your issue in as much detail as possible:

I updated Steam today, and since then it crashes upon any attempt at launching it.
When trying to launch from terminal I see this output
https://gist.github.com/adoa/188833bd0f5bd84583635ee92a49772e

Visually I see this:

I tried

• Gnome + X11→ same crash [I could provide those those logs too if you want.]
• -cef-disable-gpu → same crash

I tried looking into the coredumps of steamwebhelper, but I get many warnings like this

warning: Can't open file /usr/lib/x86_64-linux-gnu/libgtk-3.so.0.2404.20 during file-backed mapping note processing

and finally only see output like this

Thread 1 (LWP 82944):

#4  0x0000000000000000 in ?? ()

quit

I suspect that might be an Ubuntu vs Arch thing. Any tips how to make that info useful?

Steps for reproducing this issue:

1. open terminal
2. execute steam

Most likely a duplicate of #10547

I tried again with STEAM_LINUX_RUNTIME_VERBOSE=1 steam. I do get more verbose logs.
steam-logs-verbose.tar.gz
When looking into the steamwebhelper.log, I don't see any complaints about the symlinks. They seem to get resolved correctly. Is this really the culprit? The only error I see right before the crash is

[0229/233234.360978:ERROR:context.cc(100)] The browser_subprocess_path directory (./steamwebhelper) is not an absolute path. Defaulting to empty.

Since other people are experiencing issues with more symlinks, here a list of symlinks on my system that may be involved:

/home/valneq/.cache -> /data/valneq/.cache
/home/valneq/.config -> /data/valneq/config
/home/valneq/.local/share -> /data/valneq/local/share

/home is on SSD, while /data is on HDD.

I was reading up on #10552 which seems very similar. There, people mentioned bind mounts being more robust than symlinks.

I after replacing the .config symlink with a bind mount, Steam works again. 🥳

Finally, I decided to replace all three symlinks mentioned above with bind mounts.

Since this seems a duplicate, I close it here.

/home/valneq/.config -> /data/valneq/config

Based on what we have seen on other issues, I think this is the one that was actually triggering the problem, and the others were not relevant (but replacing them all with bind mounts is more future-proof than leaving the others as symlinks).
