Plays just fine for me (albeit rather choppily), with no error messages,
with SVN revision 23315 from earlier this month. My copy of the dumped
file is 2.1MB.

Your MPlayer is more than six months old and also, if I'm not mistaken,
is a third-party packaged version. Neither of these are supported here
except in corner cases. Please update to the latest SVN version (or
something approximating that) and try again.

Note also that this last message, "Core dumped ;)", is normal with the
-dumpstream option; it means that the core of the stream you specified
has been dumped to a file. Many people seem to think that this is
unreasonably misleading, but the bulk of the developers seem firmly
enough on the side of retaining the joke that it is unlikely to be
removed anytime soon.
