The problem is that those bugs are not going to be fixed, not in a
stable release and often not for years in the developement release. At
least I've seen those GLib-CRITICAL warnings for years now in some apps.

The app works so I, as user, simply don't care. Some developers also
seem to not care and software is released with those errors. The checks
in glib seem good enough to handle such cases sanely so maybe the glib
could be shut up about them for stable releases (or where users just
don't care). Maybe something like setting GLIB_BE_SILENT or so if
recompiling the lib silent is out of the question.
