Application: kontact (4.9.2)
KDE Platform Version: 4.9.2
Qt Version: 4.8.2
Operating System: Linux 3.2.28 x86_64
Distribution: Ubuntu 12.04.1 LTS

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

Closed the Akonadi tray (right mouse button, Close).  I needed to access my IMAP account directly over the web interface, it loaded my last session endlessly, so I suspected interference w/ running KMail.
The root was that KMail gave an error notification over and over again ("resouceld") that it could not create a folder on my IMAP account, so I wanted to create the folder online.

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