Application: kmail (5.19.1 (21.12.1))

Qt Version: 5.15.3
Frameworks Version: 5.89.0

-- 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
