Bug 276449

Application: kontact (4.6.0)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

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

While trying out KDE PIM 4.6 I tried to create a ToDo item from a mail. The first time I tried the ToDo item "disappeared". The second time I switch to the ToDo view apparently while the item was being syncronized to my Memotoo.com account (I guess). Crash.

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