Its not really a hang, the frontend ist still running, but vdpau doesn't
show a picture anymore.

I haven't tried downgrading yet (because its not really a solution).
But the problem was introduced by just upgrading from glibc 2.10 to 2.11
without changing anything of libX11, xcb or xine-lib, so I would guess
with glibc 2.10 the problem would not occur.

That can take some time, on my system I can't reproduce the problem, but I
have some users which can provide these traces.
