           Summary: kmail crash after double startup and closing one
                    iconified window
           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: olivier.lahaye1 at free.fr


Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
when loggin in, kamil is always double restored (seesion management bug?)

I closed one of both kmail windows and kmail crashed.

Windows were iconified, so I right clicked the kmail<2> windows and selected
close.

and boom
