Here is what gets added to the message in Console:

I'm running OSX 10.8.4 on mid 2012 Retina MBP. Spotify is version 0.9.1.57.ge7405149.
Reproduction is the same as everyone else in this thread, deleting a track seems to work just after spotify is restarted, but after some unknown event or period of time it causes spotify to crash. Here's the logging from when spotify restarts in case that helps:
