Bug 170340

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7

Description of problem:
I have a bunch of ogg files created with grip + oggenc.  Playing them results in a rhythmbox crash at unpredictable times.  Sometimes it will play for only 15 minutes before crashing, other times it will go all day without crashing.  The actual ogg files being played don't seem to have any effect on it.  The only constant is that the crash always occurs BETWEEN tracks of a CD, not during actual play.

Just before crashing, rhythmbox will spew about a million repetitions of these lines to the terminal window:

(rhythmbox:26689): GStreamer-CRITICAL **: gst_bin_remove: assertion `GST_IS_ELEMENT (element)' failed

(rhythmbox:26689): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GstElement'

Note that 26689 was the pid of the rhythmbox process.  The backtrace when crashing looks like this:

I will keep the core file from which this backtrace came for awhile in case it should prove useful.

Version-Release number of selected component (if applicable):
rhythmbox-0.8.8-2

How reproducible:
Sometimes

Steps to Reproduce:
1. Rip a CD with grip and oggenc.
2. Play the ripped CD with rhythmbox.
3. Keep playing it over and over until rhythmbox crashes.
  

Actual Results:  Rhythmbox will occasionally crash between tracks of the CD.

Expected Results:  Rhythmbox should have played the entire CD without crashing.

Additional info:

Since the crash appears to be happening down in gstreamer, let me note that I have gstreamer-0.8.10-1 installed.
