Please describe the problem:
Well, it's my firs bug report, and I didn't know if i'm doing it correctly.
But anyway, the issue is that when i am playing music, next song switches, and sometimes rhytmbox stops playback, switching takes about 10 seconds (when this bug happens, it takes about this amount of time).
To makes him play again i have to press play, and the song will then start.
My version of rhytmbox is 0.12.3, i'm using debian squeeze, the bug is also when i compiled the code or used rhytmbox from repository. 
Architecture amd64

Steps to reproduce:
1. Switching songs


Actual results:
Playback stops after taking about 10 seconds to switch a song

Expected results:
Play next song

Does this happen every time?
No
