           Summary: Kmail message window freezes and then kmail crashed
           Product: kontact
           Version: 4.4.11
          Platform: Debian unstable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: fbianco at swisslinux.org


Application: kontact (4.4.11)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I finished writing an email, then I clicked send button. The window became
gray, but then it freezes : the message window stayed green and only the
close/minimise button from the window manager were accesible. Clicking close
crashed kmail.

This appends from time to time.

The crash can be reproduced some of the time.

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