I think this started with you being told that your bug report was no
good without valgrind logs. Then you complained about that, but
eventually came back and said you had set yourself up for valgrind
reports. Then there was discussion on the need for proof that there is
a leak in the first place. Assuming you have got past that barrier
(which I am not convinced of) IMHO its time for YOU to provide
valgrind reports if you want to lodge a bug report.
