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.
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".
