Looks like it's the same as bug #173017
It is an assert failure for vector indexing being out of range, and i don't thing it is the same as the other bug you mention here: http://bugs.kde.org/show_bug.cgi?id=173017
The other bug is also an index out of range in KWin::Workspace::clientArea, it's just that for some reason the message was "optimized out" (check the backtraces).
