brasero crashed with SIGSEGV in g_type_check_instance_is_a()

Perhaps the retracer can tell if this is a dupe. It may be the same as bug 1176269, that I reported. But the retracer failed on that one. I'm not sure if it's having problems, or if there's something non-standard in this system's coredumps, or what. The circumstances were different for this crash, anyway.

I was setting up an audio CD to burn. I think the crash came as I was dragging some tracks into a different order, but I can't remember for sure. Thanks.
