I have the same problem
Ive been using amsn since i fist got my mac book well over a year ago and its worked fine until last week when i went to open it and it never loaded the contact window, instead i get that same bug report message. so then i updated to the most recent version and still nothing which is a shame because i hate real msn for the mac (it sucks sooooo bad). but not so bad that im willing to deal with this SVN crap.
It seems like some stupid preference file somewhere in the god forsaken jungle that is the mac os must have been altered or corrupted......anybody have any idea what one if this is the case....
i dont know if it will help but shortly after amsn croaked my application permissions wigged out to and it started saying i wasnt able to alter the folder (applications) and i had to authenticate every time i installed something or updated something - i fixed that issue it was a permission issue - somehow they changed them selves???!?!?
so could the issue be related since they probably happened at the same time.....?
