Description Damien Gombault 2011-10-07 08:36:26 UTC

I use only one Jabber account.

I use telepathy-glib 0.15.7

I also get in .xsession-errors file :

tp-glib:ERROR:util.c:1961:_tp_contacts_from_values: assertion failed: (G_IS_OBJECT (value))

(gnome-shell:1404): telepathy-WARNING **: tpf-persona-store.vala:617: Lost connection to the telepathy-logger service.

(gnome-shell:1404): telepathy-WARNING **: tpf-persona-store.vala:617: Lost connection to the telepathy-logger service.

The crash seems to only happen when I join a Jabber MUC.

I use :
 - empathy 3.2.0.1
 - telepathy-farsight 0.0.19
 - telepathy-farstream 0.1.1
 - telepathy-gabble 0.12.7
 - telepathy-glib 0.15.7
 - telepathy-logger 0.2.10
 - telepathy-mission-control 5.9.3
 - telepathy-qt4 0.7.3

Comment 2 Guillaume Desmottes 2011-10-11 20:28:00 UTC

Thanks for the bug report. That's a telepathy-glib crash so I forwarded it to https://bugs.freedesktop.org/show_bug.cgi?id=41697

Comment 3 Guillaume Desmottes 2011-10-11 21:25:55 UTC

I didn't manage to reproduce this bug. Does it always happen when joining a specific muc?

Nevermind, I fixed it in tp-glib.

Comment 5 Damien Gombault 2011-10-12 08:14:28 UTC

I have installed tp-glib from master this morning and I haven't get the crash.

Thank you very much.

I wonder if it would be possible to make Empathy more robust to this kind of Telepathy crash.
Instead of crashing, maybe catch the abort signal in the Telepathy code (or something like that, I'm not a C developer) then display a message to the user like « Something was wrong in a Telepathy component... ».

Comment 6 Guillaume Desmottes 2011-10-12 14:07:44 UTC

Empathy won't crash if another Telepathy component (CM) crashes. But in this case the bug was in tp-glib on which Empathy is linking so the crash was happening in the Empathy process; not much we can do in this case.

Comment 7 Damien Gombault 2011-10-12 14:10:29 UTC

OK, thank you for the information.
