Can you make sure you have SDL dev packages installed?
Something like " dpkg -l '*sdl*dev*'  "
I have version 1.2.10-3ubuntu2 on my Edgy system.
It looks like your mlt build miss the SDL support.

Hum, in KRender::createVideoXWindow(), we should return (or raise an
exception) when encountering the error instead of going ahead further and
crashing. Since the function is void, what is the Right Thing(tm) to do?

My guess would be the SDL install. Can you check whether there's a libmltsdl.so
installed in /usr/share/mlt/modules/ ?
