Maybe, but:
a) differend optimization modes for KWin/Qt (anyone -o3?)
b) Daniel only encounters it on session ends, what could suggest a general
memory corruption

However, Daniel's new trace ends up incredibly high in the stack as well, where
the first one was near the heap (@Daniel: are the numbers for
KWin::Deleted::create always that large now?) and more interestingly the OP
just suffered bad heap, but no stack deref %)

Ultimately we could simply just bypass Deleted::create() in the deconstructor
(it's pointless anyway - the compositor is gone at that time) but that does of
course not really fix the issue. :S

@Daniel:
can you try swapping the release loops for CLients and Unmanaged in
workspace.cpp ~ line 540? (It will likely still crash, but the question is
"where")
