So, my scenario was deleting from a playlist while something was playing would crash. I'd start back up, delete the track I was trying to delete (successfully this time), then start playing - the next time I deleted a track, crash. This is a "Review" playlist where, if I'm paying attention, I will move the track to another playlist and delete it from the current (review) playlist - sometimes while it's still playing, sometimes when the next track is playing.
I reinstalled about 5:30pm, and got through 3-4 delete cycles successfully, Paused for dinner, came back about 7:20pm, and my first deletion attempt crashed. I'm on Mac OS X 10.6.8. Following the reinstall, I see the following pattern every 10 seconds in the console log (I do not see it in the log before the reinstall):

Indeed, there is no SpotifyWebHelper there.
At about the crash time:
