It was intentional and was triggered by this change:

http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=f19546e02d3318ee69fd0c34e21aa97b74c987ec

which is a sanity test added to fix certain failure cases where a given
revision wasn't on a specified branch.

The bug was nasty since the fetcher was hitting the network in cases it
shouldn't have been when a branch wasn't specified.

Cheers,
