I believe I have hit the same or a closely related problem some time ago (at least judging from the backtrace) and reported it upstream, where my issue got fixed (in 3.2.3 and 3.3). https://bugzilla.gnome.org/show_bug.cgi?id=664370
Also, this report might be related to #654711 where i submitted my issue. Kai -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
