Version:           2.1 Beta 1 (using 4.2.1 (KDE 4.2.1) "release 103",
KDE:KDE4:Factory:Desktop / openSUSE_11.0)
Compiler:          gcc
OS:                Linux (i686) release 2.6.25.20-0.5-pae

I have no good way to reproduce this crash. I was playing around with different
settings in the histogram dialog. The bug appears randomly with both linear and
logarithmic.
