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 2.6.29-02062903-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I was updating a contact's address in Kontact address book part. On changing the country from Afghanistan (seemed to be default) to the United Kingdom after applying changes Kontact crashed. I tried a few variations (email changes etc) but it looks like the crash was caused in the address update particularly with the country code drop down box.
