Reported using DrKonqi
the backtrace doesn't match your report. according to it, you clicked a (probably the close?) button of the aurorae decoration, so that crash a) should go away by switching the decoration, maybe even the theme b) doesn't seem to be realted to any fullscreen action or compositing. If you can reproduce the crash (as suggested) please check whether the backtrace is equal/similar (or in doubt just attach it here)

Assuming you're using some Aurorae decoration theme: try the oxygen deco (or eg. KDE2) and please report if that "fixes" the bug so we can set it a dupe.
