I tried to delete a spam message in an IMAP folder by selecting it and pressing delete, Usually it goes to the trash folder, however this time it is crashing kmail with a floating point error signal. It is currently repeatable, however I had some similar crashes the other day and it had since stopped crashing.
When I reopen KMail the message is still in the folder as if I had not deleted it.

Backtrace:

Application: KMail (kmail), signal SIGFPE
