Some HTML5 Tools widgets cannot work with Devel generate

this is really an issue with devel_generate but I thought I'd list it here in case someone else runs across this problem. To reproduce, simply add a text field to a content type and choose the "email" widget or the "url" widget.

Then try to use devel generate to generate content of that type and watch the explosion.
