Fedora's fedpkg [1] is using GitPython in background, but unfortunately, this usage corrupts the Git repository in a way, that added files [2] always stays in staging and they never get commit. Is there any chance you could help fix this issue?

Please see more in Red Hat's Bugzilla:https://bugzilla.redhat.com/show_bug.cgi?id=822055

Also note that I tried the recent version of GitPython and pythong-gitdb without luck:

$ rpm -q GitPython
GitPython-0.3.6-0.1.fc23.noarch
$ rpm -q python-gitdb
python-gitdb-0.6.4-0.1.fc23.x86_64
