...also, tried uninstalling the package, restarting the system, then reinstalled KeePassXC from Flathub, get the same error trying to run "flatpak run org.keepassxc.KeePassXC".

[droidmonkey]

The stack smash error means there is a buffer overflow somewhere in code that has enabled that kind of protection. I doubt this is in KeePassXC code as we'd see it everywhere, plus we did not change KeePassXC code in our latest flatpak update, just the kde runtime used and Botan. Can you run diagnostics on your flatpak or gdb?

[tlcarpenter]

Willing to try (not much of a programmer). Follow the info below for Flatpak?

https://docs.flatpak.org/en/latest/debugging.html

[droidmonkey]

Yes that would be the way

[tlcarpenter]

Not sure that my environment is set up properly for debugging but I tried running

$ flatpak run --command=sh --devel org.keepassxc.KeePassXC [📦 org.keepassxc.KeePassXC ~]$ gdb /app/bin/keepassxc

the output for which included

"(No debugging symbols found in /app/bin/keepassxc)"

[droidmonkey]

That is expected, you need to type "r" then press enter to run the program

[tlcarpenter]

Thanks.

Sorry forgot after it crashes issue a bt and press enter to show the stack trace

[droidmonkey]

This isn't a KeePassXC crash. This needs to be filed with another project, I'm not sure which just yet.

[tlcarpenter]

Mine may be an edge case; seeing the GLX-related messages makes me wonder. The system I'm getting these errors on is an Apple iMac (27-inch, Late 2013) running Ubuntu 22.04.3 LTS (desktop version for amd64). It'd be nice to get the flatpak package working but I understand if there are bigger fish to fry.

[droidmonkey]

Yah this isn't a bug on our side though. I would imagine all flatpaks would fail, but maybe not. We enable a lot of security protections in our code that other apps do not.

[tlcarpenter]

Thanks for the time you put in on this.
