Description Roland "Test-tools" Bär 2007-06-27 05:09:17 UTC 
compiz/kde/window-decorator/window.cpp function KWD::Window::updateProperty (void)
line 1342.
At line 1360:   mDecor->borders (maxExtents.left, maxExtents.right,
 "mDecor" gets derefenced
Later at line 1382: 		if (mDecor)
Either mDecor should be NULL-checked before first dereference at line 1360,
or that later NULL-check is unnecessary.
