Thanks. I dumped the --show-reachable, but the major difficulty is
that this is an infinite pipeline, so there's no point at which
valgrind can dump out the memory leakage.

But I hacked gst-launch to accept a quit signal. (I can't use the
already-existing SIGINT, because valgrind catches that and dies.)

So now it's showing me a leak that I'll try to track down. I pasted
the output at the bottom. It's nothing surprising; it looks like
buffers aren't getting unreffed.

I think it was 0.10.13 originally? But I get the same thing with current CVS.
