I've also got my konsoles set on unlimited scrollback so maybe this is related to an overflow. I had a couple of very large > 200M konsole temp files when I was looking for disk space.

Has anyone reproduced this using KDE 4.8 or a recent master? I couldn't get it to crash.
Tested with a ruby script and one million of lines, no crash with KDE sc 4.8 and konsole 2.8.

Git commit af20d278710c142646fa82a494a8312fdbfdac08 by Kurt Hindenburg. Committed on 09/06/2012 at 21:49. Pushed by hindenburg into branch 'master'. check to handle issue w/ fillWithDefaultChar given huge -count Previously, the count could be a huge negative number which could exceed what an int can handle. Also, there's no reason to calculate this number if it will be negative. M +6 -0 src/ScreenWindow.cpp http://commits.kde.org/konsole/af20d278710c142646fa82a494a8312fdbfdac08
