Application: kontact (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
I right clicked the "To" box and selected the Edit Recent Contacts option. The moment I do this, my whole Kontact crashes instantly.

I am using the Google Resources from the Ubuntu 12.04 repo.

The crash can be reproduced every time.

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