Application: kontact (4.8.2)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.3.2-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:
I have setup Kontact/KMail/Akonadi to support Sieve. Kontact starts after logging in and I do not open accept the request to open KWallet by entering my password, because I am AFK. When I later come back, Kontact will have opened a window asking me for my Sieve password (and username, but that is already filled in) and the KWallet dialogue is still open. I enter my KWallet password in one dialogue and as soon as I enter the Sieve password into the other, Kontact will segfault.

The crash can be reproduced every time.

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