Complaint from git about a branch that isn't a branch, what's up?

Running command: git branch --track "rex-je-1.0" "remotes/svn/rex-je-1.0"
fatal: Cannot setup tracking information; starting point 'remotes/svn/rex-je-1.0' is not a branch.
command failed:
2>&1 git branch --track "rex-je-1.0" "remotes/svn/rex-je-1.0"

Interestingly, running the command again didn't fail.
$ git branch --track "rex-je-1.0" "remotes/svn/rex-je-1.0" [13:41:17]
Branch rex-je-1.0 set up to track local ref refs/remotes/svn/rex-je-1.0.

Duplicate of #132. Fix proposed in #145.

This should be fixed in 2.3.1. Please reopen if you find otherwise.
