After opening KMail with a local IMAP server (Dovecot) everything has worked fine for 1/2 year.

I then received one particular mail that shows in the list but when you try to view it it doesn't show up in KMail in the preview panel.

I checked the mail in the maildir former on the server and it looks perfect fine. Just plan text, no strange headers etc. However it doesn't show up.

I then tried to delete it and found out that every time I try to delete the mail in KMail it repeatedly crashes 100%

The full traceback is included below

System configuration startup check disabled.
