           Summary: konsole crashed all instances after entering tab
                    completion in zsh.
           Product: konsole
           Version: 2.4.2
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: bruce.edge at gmail.com


Application: konsole (2.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-25-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
All konsole instances disappeared after I entered a zsh tab completion mode.
There were too many entries to display and I was prompted to hit ESC to <don't
remember the rest>

Also, This was from inside of a screen session, so that may have contributed to
the odd env.
