Muon up to versions 1.01 suffers from a bug where the app will crash if the Music browser is opened and the iPod library on the device contains zero tracks. An interim workaround to prevent this bug is to add at least one music track to the device using iTunes.
Note that on devices with iOS 5.x, I have witnessed cases where over-the-air system updates can result in the iPod library being 'emptied' in cases where the update encounters an unrecoverable error or otherwise fails to complete. If muon 1.0 or 1.01 exhibits this behaviour, check that the iPod library on the device contains at least one music track.
This bug has been fixed in our codebase so as of the next release muon will no longer crash in this situation.
