I honestly don't know. It ran under trinity so I'm not sure what the exact
scenario is.

I can't seem to hit it again easily so far, it seems that many people merged their
work in the -next tree recently so I'm seeing multiple unrelated failures all over
the place, which makes reproducing this one harder.
