Try to get a jpeg snapshot through xawtv (this is the method that ZM uses) and see if that returns an image. If you are able to get a image, check the attibutes of the image and set ZM to match. If you can't get a snapshot then you might have to compile a custom kernel to support the webcam:

I don't use webcams so I really can't be of much help. I guess I'll need to pick one up so that I can learn

Check some of your other logs and you should find something more informative. Also you might try unchecking ZM_STRICT_VIDEO_CONFIG in the options panel under the Config tab.
