This looks better, but indicate that somebody smashed cleanup 
chain in request cleanup handler.  This may be easily caused by 
modules (not even talking about patches).

If you are able to reproduce the problem without third party / 
local patches and modules - please provide more details, i.e. 
debug log and config to reproduce the problem.
