Comment 9 for bug 555177

This bug happens in 10.04 both in totem and rhythmbox - when changing volume they can each segfault. Rhythmbox has reported failing the following assertion immediately before crash:

$ ./rhythmbox
(rhythmbox:10465): GLib-GObject-CRITICAL **: g_object_notify_queue_thaw: assertion `nqueue->freeze_count > 0' failed
Segmentation fault (core dumped)

I attach backtraces with debugging symbols for the crashes in each application. I hope they're helpful. As I say, the crash happens the same in each case, and as the stacks show, both programs crash after a call to gst_play_sink_set_volume takes it through g_object_notify_queue_thaw.
