Application: systemsettings (1.0)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.30-2-686 i686
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
I was actually rummaging in the menus, looking for the opacity setting, which unfortunately does not appear to be searchable as such. The problem I'mhaving is that the opacity is so low that I cannot read the screen. It was at such a moment that this program  crashed.

Thank you very much for whatever help you can be!! :)
