"should never happen" message happened

[Mathias Panzenböck]

I just noticed this message in the console output of amarok:
amarok:   [WARNING] [MountPointManager] Device  0  not in database, this should never happen!

I figured because tis is a "should never happen" message I post here to tell that it did happen. 
Whatever this message means.
