-- Information about the crash:
- What I was doing when the application crashed:
I created a new email as a forward (attachment) of another email. I alt-tabbed back to Kontact to attach a 2nd email. While dragging the email I alt-tabbed back to the composer window and Kontact crashed in that moment.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
