This renders the other bits of mopidy unusable. For example the MPD backend can't launch any music.

What were you doing when this happened? The traceback is indicating either it received bad data from the server or that the local cache in memory got corrupted somehow, which I've never seen happen

mcarlton00 commented 3 years ago

This is fixed in #82
