-- Information about the crash:
- What I was doing when the application crashed:

I had searched for a particular message using the recipient's email address. KMail found the message - one of the options was to go to the message. When this option was selected, KMail - and subsequently Kontact - crashed. 

Can be reproduced every time

-- Backtrace:
