           Summary: crash with unlimited history
                    [QVector<Konsole::Character>::detach,
                    QVector<Konsole::Character>::data,
                    Konsole::Screen::copyLineToStream]
           Product: konsole
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: simon at aktionspotential.de


Application: konsole (2.4)
KDE Version: 4.3.70 (KDE 4.3.70 (KDE 4.4 >= 20091002)) (Compiled from sources)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-rc6-git3 x86_64
Distribution (Platform): Gentoo Packages

What I was doing when the application crashed:

hi,

i run amarok -d from konsole and had history set to unlimited. searching for a
String in the output got ridiculous slow and finally (with 1,6GM Mem and 100%
CPU) konsole decided to crash.
