-- Information about the crash:
Hi,
I have setup the "Personal Contacts" in the KDE Address Book. In context menu for a address book you can select something like "copy address book folder". If you did this an then click on the "New Contact" icon, the program will crash on my installation.
I hope this helps!

The crash can be reproduced every time.
