Bug 214750

Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
While starting up kontact, nothing happens. It doesn't start and after about 5 or 6 times it shows this bug reporting window. And everytime bug reporting gui says the same thing: segmentation fault. My comptuer is updated very often, and I updated it before filing this bug

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