/usr/lib/telepathy/telepathy-gabble:5:g_source_remove:ffi_call_unix64:ffi_call:g_cclosure_marshal_generic:g_closure_invoke

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

Confirming, since that glib update Jabber (through t-gabble) cannot connect due to this crash.

Seems like it could be rather a bug in telepathy-glib, other connectors have the same issue, e.g telepathy-salut
