Version: 4.2.3 (using KDE 4.2.3) OS: Linux Installed from: Ubuntu Packages I use the command kwin --replace because after start KDE, desktop effects are starting with default settings.

> #18 0xb3aac710 in ?? () from /usr/lib/kde4/kwin3_qtcurve.so tells me it might be a qtcurve problem ;-P (maybe there's an abi incopat. due to the KDE4.2 unstable kdecoration functions?)
After start KDE I have 2 virtual desktops instead of 4, effect wobbly windows not work, I can change virtual desktop scroll of mouse (I don't like it) etc.
(In reply to comment #3) > After start KDE I have 2 virtual desktops instead of 4, effect wobbly windows > not work, I can change virtual desktop scroll of mouse (I don't like it) etc. And how is this random list of points related to the crash report? Btw 2 virtual desktops is Kubuntu default, not KDE.
(In reply to comment #3) > After start KDE I have 2 virtual desktops instead of 4, -> kcmshell desktop > effect wobbly windows not work -> plugin not loaded? > I can change virtual desktop scroll of mouse (I don't like it) etc. -> that's a plasma thing except you might wish to say you're running compiz instead of kwin (so maybe your session settings don't get store - do you lack write permissions on "~/.kde/share/config/ksmserverrc"?): how's this related to the bug report? however, before (re?)starting kwin, edit ~/.kde/share/config/kwinrc find (or add) the section [Compositing] then change or add: Enabled=false (this will disable compositing, you can re-enable it when kwin stops segfaulting) next find or add the section [Style] and change or add: kwin3_oxygen this /may/ prevent kwin from crashing as the qtcurve deco is involved in the offending function chain.
After: "edit ~/.kde/share/config/kwinrc find (or add) the section [Compositing] then change or add: Enabled=false (this will disable compositing, you can re-enable it when kwin stops segfaulting) next find or add the section [Style] and change or add: kwin3_oxygen" and restart Kwin, windows decoration disappeared. Then I reboot the system and the problem with effects settings was still. I used system settings -> default programs -> windows manager and change for Compiz Custom. After click Apply appear the window with communicate, that this windows manager didn't want start and it was start Kwin. Then effects work very good. This problem is during every start the computer.
