Thank you for your report and your investigation. Could you try to recompile libqt3c102-mt again with 'gcc-snapshot' which is gcc-4.0 version 20041231?Done. Unfortunately that's even worse. Now even texts in all top-window menus don't show up. And the tree widget in kcontrol looks seriously broken.I'm going back to libqt3c102-mt compiled with g++-3.4. But I'm willing to do more testing if you tell me what to try.Thank you for your test. I will try to find out what is going on with gcc-4.0 here.
I got one more idea.I installed the binary libqt3c102-mt again (the one that was compiled with g++-4.0 and gave me the problems the Plastik widget style). I also downloaded the kdeartwork source package (in includes the Plastik theme) and compiled it with the same compiler (g++-4.0). I installed the resulting kdeartwork-style*.deb. And it works! So the problem is not g++-4.0 itself. The problem seems to be some binary incompatibility between libraries compiled with g++-3.4 and g++-4.0.
