According to this:  
http://stackoverflow.com/questions/13425298/git-submodule-update-fatal-error-reference-is-not-a-tree  
, this is most likely a maintainer's bug. From the above:

"This is the most common problem with submodules. The commit that you are  
on in the outer repository has a reference to a commit in the submodule  
that someone did not push up yet. It's a dependency problem. Always push  
 from the inside-out. This is most likely not something you did wrong, but  
someone else that's working in the repository. They were sloppy and forgot  
to issue push on the submodule and just pushed the containing repository.  
Stuff works on their machine because they made the change and those  
commits exist there."

Is this true?
