Looking at the repo itself, there also seems some data corruption, in particular the upstream info seems to be deleted:

C:\Users\anthoff\.julia\v0.5\DataStreams [0.0.6]> git status
On branch 0.0.6
Your branch is based on 'origin/0.0.6', but the upstream is gone.
  (use "git branch --unset-upstream" to fixup)
nothing to commit, working directory clean
C:\Users\anthoff\.julia\v0.5\DataStreams [0.0.6]>

possibly duplicate of #17146

Looks like an exact dup?
