-- Information about the crash:
- What I was doing when the application crashed:
I created a folder and a filter that has mail automatically directed into this folder. I edited the folder properties and turned off the "Act on new/unread mail in this folder", pressed ok, did some other things for a bit, then went in a changed the option back on. After exiting the properties dialog I clicked on another folder and that's when kontact/kmail crashed.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
