DrawableComposite problem with DrawableText?

I’ve been banging my head against this all day. Is there a bug with DrawableComposite or DrawableButton when using DrawableText? I’m able to get both DrawableComposite and DrawableButton to work fine with DrawablePath and DrawableImage, but whenever I introduce DrawableText to the operation (which is what I really need in this case) my program crashes.

Anyone?

well where does it crash?
