           Summary: kmail crashes upon click on the tray icon
           Product: kmail2
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: yannek at web.de


Application: kmail (4.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
After booting the computer and logging in,  kmail started automatically, new
mails were found and shown per number in the icon. Upon clicking on the tray
icon kmail crashed.

This happens every time on a fresh computer start if new mails are indicated
and kmail is unminimized for the first time. After restarting of kmail
everything works as expected.

The crash can be reproduced some of the time.

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