gedit git plugin crashes on local git repository

[Dmitriy Geels]

I get the following output in console:

dmig@dmig-Inspiron-5379:~$ gedit workspace/howdy-test.py
Traceback (most recent call last):
  File "/usr/lib/x86_64-linux-gnu/gedit/plugins/git/appactivatable.py", line 89, in get_repository
    repo = self.__git_repos[repo_uri]
KeyError: 'file:///home/dmig/workspace/form-observer/.git'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/x86_64-linux-gnu/gedit/plugins/git/windowactivatable.py", line 298, in inserted
    repo = self.get_repository(location, msg.is_directory)
  File "/usr/lib/x86_64-linux-gnu/gedit/plugins/git/windowactivatable.py", line 282, in get_repository
    return self.app_activatable.get_repository(location, is_dir)
  File "/usr/lib/x86_64-linux-gnu/gedit/plugins/git/appactivatable.py", line 95, in get_repository
    head = repo.get_head()
gi.repository.GLib.Error: ggit-error: reference 'refs/heads/master' not found (-9)

The reason is simple ~/workspace/form-observer/ is a local-only repository, it has no remotes. But it is weird for me, why this plugin scan subdirectories?
