Crash before UI launch with SIGABRT / IOT instruction

[flferretti]

Hi! I tried launching pixi-gui on my system, but it crashes instantly:

pixi-gui --no-relaunch
panicked at library/core/src/fmt/mod.rs:2736:38:
thread panicked while processing panic. aborting.
[1]    3265297 IOT instruction (core dumped)

The crash happens before the UI loads. My CPU supports CET/IBT (ibt and user_shstk), so it might be related.

Hmmm... The double panic makes it a bit tricky to debug this, as we can't see the actual root cause here.

Can you try running with

• WEBKIT_DISABLE_COMPOSITING_MODE=1 pixi-gui --no-relaunch
• WEBKIT_FORCE_SANDBOX=0 pixi-gui --no-relaunch

Are you using any other containerization, like Distrobox or Fedora Toolbox? Are you able to use other Tauri applications (for example GitButler)?

Are you able to render web content with Liferea? If yes, which version of webkit2gtk4.1 do you have installed on your system? (Liferea uses the same underlying webkitgtk)

Thanks @haecker-felix, I tried what you suggested and I still get errors:

fferretti@gblaptop0047:~% WEBKIT_DISABLE_COMPOSITING_MODE=1 pixi-gui --no-relaunch

Yes, I can open GitButler and I'm not using any containerization and I'm on Ubuntu 24.04 with i3 WM

I'm able to open liferea, which links to libraries installed via APT:

% ldd $(which liferea) | grep webkit

	libwebkit2gtk-4.1.so.0 => /lib/x86_64-linux-gnu/libwebkit2gtk-4.1.so.0 (0x000070de15600000)

and pixi-gui was using:

fferretti@gblaptop0047:~
% LD_DEBUG=libs pixi-gui 2>&1 | grep -i webkit
   1620119:	find library=libwebkit2gtk-4.1.so.0 [0]; searching
   1620119:	  trying file=/home/fferretti/.pixi/envs/pixi-gui/bin/../lib/libwebkit2gtk-4.1.so.0

   1620119:	calling fini: /home/fferretti/.pixi/envs/pixi-gui/bin/../lib/libwebkit2gtk-4.1.so.0 [0]

Now that liferea installed libwebkit2gtk-4.1, after uninstalling pixi-gui and reinstalling it via pixi global, it works
