KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1

-- Information about the crash:
I was investigating an akonadi issue similar to the on discussed at http://forum.kde.org/viewtopic.php?f=20&t=85072.

Having restarted akonadi (akonadictl stop, akonadictl start) I restarted Kontact and could now reach the calendar component. When right-clicking on akonadi resource in the list of calendars, the menu briefly appeared and Kontact crashed.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
