@gajim Still got a bug when I try to install it. There once was an update and since then I can't use Gajim at all. :/
If anyone can help, the bug is the following : gi.repository.GLib.GError: gdk-pixbuf-error-quark: Unrecognized image file format
Edit: tried everything on this page https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues/159
But it didn't solve it.
