debug log and screenshot of the output

Trying to render yet another project ("présence et robotique"), and getting an
output that does not match with what I see when doing live playback while
editing. Right after the first clip, when "switching" to the second clip, the
rendered output looks garbled (screenshot inside the tarball).

I have tested this with pitivi git, pitivi 0.13.3, with gstreamer packages from
the PPA and with vanilla gstreamer packages from Ubuntu 9.10.

Attaching the output of
GST_DEBUG=3,gnl*:5,*ERR*:5,python:5 PITIVI_DEBUG=5 bin/pitivi > debug.log 2>&1;
