           Summary: crash opening attachment with kwrite, closing it
                    before contents are inside
           Product: kontact
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: kde-bugreport at zmi.at


Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.1 (KDE 4.3.1) "release 6"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
kmail crashes when I click an attachment, open it with kwrite, but close kwrite
before kmail put its content there. Looks like a timing problem, similar to
