          Reporter: ingo at fivemile.org
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED

           Product: kontact

Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:

Selecting a HTML mail with external references enabled => crash
Selecting a HTML mail with external references disabled, manual loading of
