From what I can tell, when loading banshee and having a volume mounted that has symbolic links e.g. Ubuntu 10.04 ISO/CD - after it tries to follow the symbolic link for a number of times, it causes Banshee to crash when adding music to the library. When I unmount the volume it doesn't crash any more. This bug does not always reproduce as it's not happening now with the volume mounted.

steps:
1. Have a Ubuntu CD or Ubuntu CD Drive mounted
2. Open Banshee
3. Wait for it to scan your files, initially.
4. It crashes giving the following Warnings
