           Summary: KVirc crashes if user is connected to several servers
                    and close the main window of one of them.
           Product: kde
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: xarion at rootnode.net


Application that crashed: @^
Version of the application: 4.0.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.13-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
1. Open KVirc
2. Connect to some server.
3. Click "New context" button.
4. Connect to another server in window created by "New context"
5. In "Window List" click right mouse button on the main "window" (represented
by the icon of server) of a new connection and select "Close window"

The names of the menus will vary because I use the Polish version of kvirc.
Sorry if what I wrote is not entirely clear but my English is not too good:)
