Application that crashed: kompare
Version of the application: 4.0.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12 i686

What I was doing when the application crashed:
I reviewed the next stable kernel patch (kernel.org/pub/linux/kernel/v2.6/stable-review/patch-2.6.32.8-rc1.gz)
against current stable kernel 2.6.23.7 :

After I pressed 16x Ctrl+PgDown it crashes (relyable) :

tfoerste@n22 /usr/src/linux-2.6.32.7 $ kompare /usr/portage/distfiles/patch-2.6.32.8
