yes I confirmed this.

This happens because we've overridden the loadImage() method to create a 
GLTexture directly instead of a PImage. But if we arent on the render thread 
this will fail to create the gl texture object.
So I added a check to only create a gltexture if on the render thread - else we 
just create a PImage as in the old verions.

So fixed for the lates branches/new

thx for reporting
