-- Information about the crash:
When I was switching to an other component (with the sidebar, to the mail compontent IIRC) the mouse pointer changed to the waitigin pointer. Then I changed to the overview component but the mouse pointer didn't change back. Then I closed Kontact via the KMail systray icon and Kontact crashed.

 -- Backtrace:
Application: Kontact (kontact), signal: Aborted
