I used DDD, it works reasonably well. I figured it out where the
problem is, and I have to apologize, it was because it couldn't read
the ondrej.ogv, because I had it in a different directory and I didn't
notice, sorry for that!

Nevertheless I think it could give a more useful error message,
something like "cannot read ondrej.ogv" or something.

Anyway, it works now as expected. Anyway, the version in ubuntu still
segfaults even if the file is there, so there was some bug, but the
version 0.9.9 works fine.

P.S. That's why I like Python, that it gives you a useful traceback
right away, instead of silently failing or just segfaulting.
