Steps to reproduce:
I ran rhythmbox from a terminal.
I opened the preferneces and switched tabs and I got this crash error in the terminal

Rhythmbox is now hanged indefinitely but it doesn't exit by itself. 
System: Linux 2.6.22.1 glibc 2.6 and gcc 4.2

Stack trace:
 *** glibc detected *** rhythmbox: double free or corruption (fasttop): 0x08597c48 ***
