I'm heading out, but wanted to send an update. I can confirm that
there are some issues on master as it currently stands .. but the
good news, is that in my queue of changes for Yocto 1.7, you can
seamlessly add fragement support to that recipe and it works.

I'll be looking at this again later, and will send a branch reference
for testing. I need to bisect for the particular change first, since
the entire queue can't go into the tree yet (it breaks some use cases).
But I will submit the ones that fix this case.

Cheers,

Bruce
