I wonder if for some reason your new version of Git is honouring the shallow clone option (--depth 1), whereas my old version is not.  I'm not sure why we do a shallow clone by default; it means that you can't use the git repository for anything particularly useful.  Possibly also you can't use it for switching branches.  

The documentation says:

--depth <depth>
Create a shallow clone with a history truncated to the specified number of revisions. A shallow repository has a number of limitations (you cannot clone or fetch from it, nor push from nor into it), but is adequate if you are only interested in the recent history of a large project with a long history, and would want to send in fixes as patches.

Can you try it without the --depth 1 option and see if that fixes it?
