While using Banshee in a somewhat slow machine, I got this exception:

[Warn  20:16:30.146] Caught an exception - Collection was modified;enumeration
operation may not execute. (in `mscorlib')

One could think that this is a Banshee's bug, a threading issue. However, how
can this happen in a foreach loop which iterates through a
ReadOnlyCollection<T>? The collection cannot be modified. I'm guessing it's a
mono bug then, not sure if belonging to runtime or class-libraries.
