ZeroDivisionError: division by zero

location: <unknown location>:-1

location: <unknown location>:-1

Both Image.pixels and Image.channels return 0 in this case, which causes the error to occur.

The best way to fix this seems to export the default texture (empty string "") and let the exporter show a warning in Blender.
