It's failing because there is a bug in the code for 'git pull --rebase --recurse-submodules'
when the current branch and its remote-tracking counterpart have no fork-point,
which seem to be the situation happening here.

I've just finished a patch series that fixes this bug. You can take a look at it here:
https://github.com/gitgitgadget/git/pull/789. I will send it to the list shortly, and will
CC you when I do.

Cheers,

Philippe.
