Solution

As Lanny stated in the comments, this error occurs when you pass an invalid image (empty, not fully loaded, corrupt, 404, etc) into beginBitmapFill.

Confirm that your image is loading properly.

I just pushed an update to EaselJS NEXT that bypasses this RTE, and ignores invalid bitmap fills.
