Bug 259874

Application: kded4 ($Id$)
KDE Platform Version: 4.5.85 (4.6 Beta2)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-rc5+ x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
Hello everyone.

Everytime i start KDE 4.6beta, i get this crash. Seems to be related to the new upower backend - maybe it wants to set backlight brightness or something.

Thanks for your work guys!

The crash can be reproduced every time.
