That bug has been described on

"Using a automatic playlist with only unrated (rating=0) songs, rhythmbox will
crash if you click on the songs rating quickly and repeatedly (songs will be
removed from the list if their rating goes up). This is probably a race
condition problem.

To reproduce the bug:
1) Make sure you have songs with zero rating (no stars)
2) Create an automatic playlist matching only zero rated songs (no stars).
3) Don't enable shuffle
4) Start clicking on the rating of the playing song and keep clicking until it
crashes (about 10 to 20 songs on my machine). Clicking will bring up the song
below it and remove the song from the list. If you click fast enough rythmbox
will crash.

Misc info:
rythmbox 0.9.6
gstreamer 0.10
Ogg Vorbis music files

Crash report file

Here is a complete report from the "Problem report for" help program. Due to
the ease with which this problem is recreated I havn't taken the time to
install the debugsysms for the used program. And the problem can simply be
avoided by clicking more slowely or simply turning on shuffle so it is
impossible to click on song that just started playing.

Hopefully, this report does add something however."
