re-bake fails in example project

Hey @shadecoredev,

Thank you for open sourcing your project and addon! This looks really good. But unfortunately if try to bake in the example project with the provides model I get the following debug output:

Detected 1 animations. Detected 7 frames. Detected 3986 vertices. Added anmiation "Idle" to the animation list. ERROR: Image width must be greater than 0. ERROR: Image width must be greater than 0. I'm using v4.4.1.stable.official [49a5bc7b6] Maybe I'm doing something wrong or miss something? Any help would be appreciate!
