I'm not sure what to make of this; all indicates there was a crash deep
inside Glib, that's not really something directly affecting
modemmanager, so I've reassigned this to the 'glib2.0' source package.

Are you still able to reproduce this crash? There has been changes to
glib since this bug was reported, so this might have been fixed already.
