Well perhaps that's part of the difference. I am a developer, not of mplayer
of course, but other software.

Heh, I suppose it's useful to have someone send write up this flame
periodically. Not really relevant in this case but at least this way some poor
newbie doesn't have to suffer and might see this message before posting.

I think I detect the source of the frustration though. It suspect people just
don't believe me that it happens on every single movie. They really want to
see output from mplayer and a sample movie file and think if they just saw
that they would be able to reproduce it. 

Looking at the backtrace I really don't believe that. I believe the bug is in
the option parser for some module that builds on my machine because of the
available libraries that perhaps isn't building on your machine because some
of those libraries aren't available.

Just by way of demonstration, I can reproduce the bug playing /dev/null with
the null video output driver. Incidentally, there seems to be a different bug
in that the x11 driver is shut down at the end even though it was using the
null driver. Or perhaps that's just a quirk of the sig11 handler?

I don't think this output is actually useful to help debug, the backtrace
already made this conclusion pretty obvious. But perhaps people were
skeptical?
