GLib-GObject-CRITICAL on Steam games made by Curve Digital

When running Serial Cleaner (a Steam Deck verified game)

Previous posts about this error pin a wxwidgets update as the issue, but that was several versions ago, and the issue has apparently been fixed since then in ver 3.2.4-1.1, as I'm using 3.2.8.1-1. https://bbs.archlinux.org/viewtopic.php?id=289541&p=2
I've reinstalled the gnu packages in ccase gcc was the issue's source, but the problem persists.

I haven't been able to find much on the plugins and which packages should contain them. Is there a way to find that out?

Re: GLib-GObject-CRITICAL on Steam games made by Curve Digital

glib gobject errors are from glib2 and/or lib32-glib2 respectively (they are not and have no relation to glibc) but these errors can show up during normal operation so I'm strongly assuming a red hering.

Do you get an actual checkable dump in that /tmp/dumps it talks about, or maybe even an observable coredump? https://wiki.archlinux.org/title/Core_d … _core_dump

Re: GLib-GObject-CRITICAL on Steam games made by Curve Digital

Mhm if it dies in libc already probably some compat issue with the newer glibc and an older glibc the game used for the build, e.g. similar to the stuff that lead to https://gitlab.archlinux.org/archlinux/ … /issues/19

I'd say the most usable quick fix for this is to just use the Windows version via proton.
