Rhythmbox deadlocks, possibly since glib 2.15.3

[Frederik Himpe <fhimpe telenet be>]

The last few days, it sometimes happens that Rhythmbox 0.11.4 start 
hanging when I click on the Next button. Looking at the gdb trace, it 
seems like some kind of a deadlock, possibly in glib which I updated 
recently to 2.15.3. Is that possible?
