Description:

Since today I noticed following messages spamming syslog when ff is running:

(/usr/lib/firefox/firefox:8369): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(/usr/lib/firefox/firefox:8369): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

I've seen single occurrence of similar messages in the past but now there are dozens of those happening every few minutes. This happened shortly after I updated plasma session to 5.20 which may be relevant, I didn't test in other DE. I tested it with fresh ff profile.

Additional info:
* ff 81.0.2
* KDE plasma session 5.20

Steps to reproduce:
Launch ff and observe session logs.
This task depends upon

I use GNOME 3.38.2 and I do not have this issue.
Is maybe KDE plasma-specific?

Maybe. I don't know how to check about what /usr/lib/firefox/firefox:8369 line refers to.

So the problem seems to be "gtk-modules=window-decorations-gtk-module" line in "~/.config/gtk-3.0/settings.ini" which is automatically added by kde-gtk-config (when gtk theme is being changed in kde settings). After removing this line the spamlog is gone. It seems to be an upstream issue not related to Arch.
