[CsMain] can't load map [Could not find material]

[C. D. <cer...@gm...>]

Hi,

I created a track in blender and when I try to run it throw blender2crystal
or throw a binary I get the following:

crystalspace.maploader:
  Could not find material 'pista.png'. Creating material. This behaviour is
  deprecated.

And then the program segfault. Any hint about what I'm doing wrong?

Thanks,
Carlos.
