-- Information about the crash:
Click on the message, scroll to the attachemnts area. Opening the attachment or
trying to save it crashes kmail about 90% of the time. The attachment in
question is a pdf.

I've had this happen many times on previous versions of kmail as well.

My email provider is gmail configured as POP3.

The crash can be reproduced most of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
