Public bug reported:
Affects: rhythmbox (Ubuntu)
Severity: Normal
Priority: (none set)
Status: Unconfirmed
Description:
There seem to be a couple causes for this.
1) Sometimes switching between two of the default ubuntu ogg streams
(http://ubuntu.hbr1.com:19800/trance.ogg or ambient.ogg) will cause
rhythmbox to crash. This happens seemingly random, but only after
playing a stream for a while. Using the pause/play button to turn the
stream off somtimes causes this.
2) When the end of the stream is reached, instead of either stopping
playback or reconnecting to the stream, rhythmbox crashes.
Reproducing this bug is a pain because the conditions seem random for #1
and you've got to wait for the ogg stream to end for #2, which only
happens every 30-90 minutes.
Here's somg GDB info:

Above is general debug information generated while rhythmbox was playing
the streams normally. Below is what happened when I was switching
between the trance and ambient streams.
(rhythmbox:17907): GStreamer-CRITICAL **:
Trying to dispose element preroll_audio_src1, but it is not in the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.
