Looks like a ghost handling problem in the smart server.

Interesting....
I was seeing this with a --dev6 branch, but I thought it was just the new format.
And I'll mention that it breaks for *local* branching there, which means it would not be a Smart Server issue specifically.
Also, when I tested it, it was breaking while fetching 'revisions', so it wouldn't be caused by the new 'fill in parent inventories' logic.
I was talking about this on bug #336383
Aaron, can you confirm whether you can reproduce this branching locally into a standalone branch?
