if you add kbandwidth to kicker and then start kicker from console, you'll see a lot of warnings: QPainter::begin: Painter is already active. You must end() the painter before a second begin() (actually one warning per refresh) i think qpainter is already started by constructor and should not be started by programmer
Created attachment 138544 [details] patch for ebuild, which fix the problem by removin p.begin() from sources
Thanks, mkay! Fixed in CVS.
