My guess is that corruption is happening somewhere before the crash location so
here's the output of running with -d from where I removed a track from the
playlist - which forced the generation of an additional track from the dynamic
playlist. Just in case it's of assistance!

Is the amarok:       [WARNING] [Bias] Received more results than expected. 
of significance? I sometimes see when a track is removed from the playlist (by
one scrolling off the top) the number of tracks shoot up and then come down
again when the next (just one!) dynamically added track is added
