Description of problem:
When I got rhythmbox running with DAAP ("iTunes") sharing enabled, and try to access the share from iTunes, rhythmbox crashes.

Version-Release number of selected component (if applicable):
rhythmbox-0.13.2-1.fc14.i686

How reproducible:
always

Steps to Reproduce:
1. Launch rhythmbox
2. Enable DAAP sharing if not enabled already.
3. Open iTunes (and possibly another rhythmbox on another fedora machine, not tested) and click on the share.
  
Actual results:
Rhythmbox crashes and disappears from the iTunes menu

Expected results:
The shared music should be accessible, like in F13

Additional info:

Console output on crash:

*** glibc detected *** rhythmbox: double free or corruption (fasttop): 0x09ef0178 ***
