It does not seem like you set the correct environment variables, as I
can still see random things caused by valgrind not understanding the
slab allocator. Additionally, please try and use a suppressions file.
I recommend the one in Clutter's tree:

   http://git.gnome.org/browse/clutter/plain/tests/data/clutter-1.0.suppressions

OK, tried with G_DEBUG & G_SLICE set,

G_DEBUG=gc-friendly G_SLICE=always-malloc valgrind --leak-check=full --show-reachable=yes --log-file=3.log --suppressions=clutter-1.0.suppressions gnome-shell --replace

The log is here: www.xiahaiqu.com/3.log.gz Still got lots of leaks, but most of them originated from libmozjs and libGL. Leaks originated from libGL not necessarily means bugs in nvidia driver, might be incorrect use of opengl.
