Hi, I think I've got this problem, too.

https://bugs.launchpad.net/bugs/840854 Title: rhythmbox randomly crashes at the end of some tracks Status in “rhythmbox” package in Ubuntu: Confirmed Bug description: I have been experiencing this for the last few weeks. Rhythmbox will randomly crash at the end of some tracks. Basically it will get to the end of a track and stop playing. go back and double click on the next track in the queue and it freezes up, ultimately getting a force quit message. this happens totally randomly maybe 4-5 times per day. it seems unrelated to the actual mp3's that are playing as in its not particular files that cause this to happen.
