Comment 1 for bug 1257686

The issue seems to happen every time the status change (e.g when you get online), when using glib 2.39

The issue has been reported on launchpad, https://bugs.launchpad.net/ubuntu/+source/telepathy-gabble/+bug/1257686

The glib change that makes it error out on such invalid use is
https://git.gnome.org/browse/glib/commit/?id=a919be3d39150328874ff647fb2c2be7af3df996
