-- Information about the crash:
Moving around a lot of mail I have encountered a large number of bugs,
especially between imap servers. In this case I had moved the failing to sync
mail locally and was marking it all as read, there are a lot of folders, I was
systematically marking them as read. There is a propagation delay, if you mark
the same folder as read before it completes, especially if there are 1,000+
messages in it, kmail will crash. 

It will get into a state where it will crash every time you mark it as read
even just after opening it. I haven't tried logging out / logging in again but
I suspect based on the other errors that will "resolve" it.

The crash can be reproduced every time.
