[kdenlive] Black video when rendering with v0.9.10

[Narcis Garcia]

/usr/bin/melt was already correctly set.
Tried the script way and it renders same way as from GUI: no error
messages, black video track.

I've checked that this problem occurs with any coded profile I've tried
(H.264/AAC high, DV PAL 4:3, WebM, AVI XVid4).
I've observed that "generate script" action saves an .mlt file, and this
XML file contains a <playlist id="black_track"> clause.
Is this only related to fade_to_black?
