This is the terminal output:

This is probably a bug, and may be related to this similar one concerning Rhythmbox and UbuntuOne. –  user76204 Feb 9 '13 at 22:17
Segmentation faults are always a bug. This should never happen. Removing all user perferences/cache/library is a work around, but this does not change the fact that this is a bug report and they should belong on a bug tracker. I'm voting to close this question for off-topic as per the FAQ. –  gertvdijk Feb 9 '13 at 23:44

I just solved this issue by deleting all the user preferences, library, and cache used by rhythmbox.
