Rhythmbox crashes every few seconds

Thanks for your bug. Does it crash during the import or after? Could you install gstreamer0.10-plugins-good-dbg to get a debug backtrace? Could you run "rhythmbox -d" to figure on what file it chockes and maybe attach the file to bug?

After. I should note that I have Rhythmbox set to watch my home directory though. I think that's related. See below:

Launchpad really really really wants me to say something here.

The backtrace is similar to http://bugzilla.gnome.org/show_bug.cgi?id=336244 upstream, which is marked as a duplicate of a bug fixed with gst-plugins-good0.10 CVS code. The package will likely we updated before dapper, let we know if the upgrade fix the issue

What does "gst-launch-0.10 -v -t filesrc location=gaim_info.png ! decodebin ! fakesink" do on it?

With gstreamer0.10-plugins-good 0.10.2-2ubuntu2, the output is:
