Repro Steps

1. Clone this repo.
2. Checkout test branch.
3. Modify Class1 and attempt stash via GitStash. Error displayed is perhaps you have untracked files, and didn't select Untracked.

Notes

1. At first, I only had a master branch. The above steps worked fine.
2. As soon as a I added the test branch and tried stashing changes on it, the error occured.
