           Summary: Kmail crashed while opening digitally signed email
           Product: kmail
           Version: 1.13.5
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: giacof at tiscali.it


Application: kmail (1.13.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

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

I tried several times to select an email signed with a digital certificate, but
the message could not be displayed on the preview panel. Rather, Kmail froze
and I had to kill and restart the application. In the last attempt, Kmail
crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
