-- Information about the crash:
I'm not sure what operation is causing the problem here, but when I delete more than one message or I am queuing up multiple operations, especially when combining operations which write and read from the folder (E.G. -- Moveing a few messages, and while those operations are copmleting, delete another message, and further still select a new message to read or move), I'll get this sort of crash. I can replicate it pretty reliably, but I haven't figured out exactly what causes it aside from just queuing up a lot of operations in semi-rapid succession.

The crash can be reproduced every time.
