Application: kontact (4.9.5)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I was writing an email. I clicked on "Select..." in order to add a recipient. in the "Select Recipient" dialog I started typing in the "Search" box while the Contacts tree was still loading (i.e. with a spinning icon still running). This is enough to crash the whole kmail/kontact and it's always reproducible.

The crash can be reproduced every time.

-- Backtrace:
