Comment 3 for bug 780595

Still can't find a way to reproduce it... :S

However, I will put up an update (in the next few minutes, it will be in the ppa) with a workaround to at least allow you to go to the Preferences and choose a dir again to see if it fixes. Also I will make it write some debug info to the terminal, please post it here so I can figure this out and (hopefully) correct it.

Just as a sidenote, ~/.tagplayer_library (which is now followed by a number) stores the library's metadata only, not the user's preferences, those are in couchdb.
