Freron MailMate

I tried to expunge deleted messages in a mailbox, and MM hung. I waited about five minutes, then force-quit it. Here's the beginning of the crash dump info (the whole thing wouldn't fit, and I couldn't upload a file because it says "Upload Quota Reached. Please notify the account owner."):
