I found out what is really happening, the Lens Distortion node sets the alpha to 0 in the entire image, making output renders be transparent

Note that lens distortion only works doing some crazy "wavelength" stuff, ignoring alpha altogether (of course).
Best improvement I can do is to just set alpha 1.0 for the entire image. This node should be documented as such... after operation, alpha is cleared to 1.

Goes to svn now.

good enough, other solution could be just pass the same unmodified alpha

anyway thanks for fix :)
