Are you sure? Let me give a hint: bug 1882947
Comment 13 Edward 2020-10-21 14:59:37 UTC 
Interesting. Was using the MATE desktop at the time. And glib2 was updated since then. 

There is another updated version (2.66) but Fedora Kojiweb is not showing a package for Fedora 32.
Comment 14 Michael Schwendt 2020-10-22 13:34:35 UTC 
As mentioned, nothing in the glib2 update news indicates that it would fix such an issue.

Again it's a crash deep in GTK+2 as a result of changing a theme and the code going through gtk_rc_settings_changed --> IA__gtk_rc_reparse_all_for_settings. In the older ticket to theme "Mint-Y-Red". In this ticket to "Menta".
