The backtrace doesn't match your problem description. It hints a crash when removing a window out of the window tiling system. The problem you describe is likely related to a broken OpenGL implementation. a) you might try the xrender backend instead ("kcmshell kwincompositing" / advanced tab) b) please specify your hardware and driver, in doubt attach the output of glxinfo ("asus eee box like" can mean intel or nvidia ION - in the latter case, try installing the nvidia CSS driver instead of nouveau) c) neither compiz nor kwin developers are mad enough to block their functionality while the other one can be found on disk - that's not related ;-)
*** Bug 280741 has been marked as a duplicate of this bug. ***
D'ooh: Client *c = activeClient(); if (tilingLayouts.value(c->desktop())) { .... surprisingly there might be no active client at all, and then c is (drumroll) NULL.
