Intermission 2: Rhythmbox / Gstreamer bug

Rhythmbox keeps going silent or freezing for no apparent reason, after playing a few songs. After a restart it works again. I've had a similar problem with Spotify (through Wine) for some time, but Rhythmbox has only done this after I installed Ubuntu 9.10.

So I've filed a bug (possibly for the first time!)
Edit: Here's the bug in Bugzilla - filed by someone with the same issue.


Here's the error thrown by Rhythmbox:

(rhythmbox:3886): GStreamer-WARNING **: Element bin2 already has parent

(rhythmbox:3886): GLib-CRITICAL **: g_str_has_prefix: assertion `str != NULL' failed

Maybe it's supposed to be a Gstreamer bug, I hope some friendly developers can help me sort it out.


Edit:

When Spotify goes silent, this is the message in the console (repeated endlessly):

err:wave:wodPlayer_WriteMaxFrags Error in writing wavehdr. Reason: Input/output error

Googling it doesn't give much insight... Maybe another bug to file? The question is what package to file it for.
