Bug 333610

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.

Application: konsole (2.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 7.4 (wheezy)

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