Bug 220418

Application: kontact (4.4 pre)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
Before it crashed, I created a calendar event for an event next week, using an Akonadi calendar resource as the default. It starts at 9:00 AM, but I created it at 8:00. On dragging the event from the latter time to the former, Kontact froze indefinitely, not allowing me to interact with any elements in the window. Strangely, the UI still updated when I resized the window, but other then that it was completely frozen, not allowing any user input. It would not exit properly either, so I had to kill it, which resulted in this crash information.

The crash can be reproduced everytime.

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