transition_luma uses fezzik to auto-load PNG. On my system, I have the
gtk2-based pixbuf producer, and when it is using that, it works. Maybe
there is a problem if you only have qimage. Now, I just tried with
qimage, and it worked. However, when I ran it with "-profile
square_pal" it crashed in filter_resize - part of the image resolution
normalisation applied by fezzik. If I add "distort=1" to the end of
the command line, it works. Can you test with that?

I have to look into the details of the filter_resize crash.

Actually, it loads pgm if present and png if not. pgm is preferred
since it can be 16bit.

I could not reproduce this. '%' prefix makes it compute a path. Add a
printf after line 400 in transition_luma.c to print the computed path,
and see if it is valid.
