Application: kontact (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.3.8-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:

The compose window was open with a reply to a message. I had written something into the "To" field. Then I clicked on "To" to see what that button does. (It shows "To/Cc/...") I didn't change anything. Then I right-clicked on the To entry field because I was unhappy with the way it was suggesting addresses. In the right-click popup menu there was an item for Addressbook completion. I moved the mouse pointer there. (Maybe I clicked on the text; it had a > mark for a submenu.) That action crashed the KMail.

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