           Summary: Crash after splitting views + detaching tabs + closing
                    remaining view
           Product: konsole
           Version: 2.6.3
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: ehabkost at raisama.net

Application: konsole (2.6.3)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux x86_64
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:

1. start konsole
2. crate new tab (so you now have 2 shell tabs)
3. split view left/right
3. right-click at first tab in the left view, detach tab.

- now you have two windows:
  window A) one view, one tab: shell 1
  window B) two views:
     view B1) one tab: shell 2
     view B2) two tabs: shell 1; shell 2

4. drag the tab on view B1 to window A
5. focus on view B2
6. Menu: View / Split View / Close Active

- You'll get an empty Konsole window with no tabs or terminals

7. Menu: View / Split View / Split Left/Right

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
