notify-send crashed with SIGABRT in g_return_if_fail_warning()

[Fabien Tassin]

Binary package hint: libnotify4

I find this regularly in my /var/crash.
It's from a script doing something like:

notify-send -i /usr/share/icons/gnome/48x48/status/dialog-warning.png foo

works most of the time, but sometimes dies with:

GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
aborting...
Aborted (core dumped)

I can reproduce easily.

It started on 2011-02-14.

[Fabien Tassin (fta)]

seems to be a regression in the last dbus-glib..

[Vsevolod Velichko (torkvemada)]

with libnotify-bin 0.7.2-0ubuntu2 problem can be reproduced.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.
