            Bug ID: 333610
           Summary: konsole crash by loocking at very much output
    Classification: Unclassified
           Product: konsole
           Version: unspecified
          Platform: Debian stable
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: history
          Assignee: konsole-devel at kde.org
          Reporter: dosm.mail at gmail.com

I've written a programm in java that makes whery much output. After terminating
the programm using ksysguard I wanted to read the output. As I brought back the
konsole into foreground, I saw that the konsole-screen was kompletely black
except for the prompt at the end of the "page". I tried to scroll up. Then the
konsole crashed.

Reproducible: Didn't try



Expected Results:  
Konsole should have showed the output.

Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-amd64 x86_64
