Comment 1 for bug 1005946

Does better after several updates to Ubuntu. But still crashes occasionally.
This mornings update did cause Docky to abort. Luckily, I was in debug mode so I captured the dump from mono:

[Fatal 08:58:01.057] [GLib-GObject] g_object_ref: assertion `G_IS_OBJECT (object)' failed
