Hi all,

Unfortunately, and sorry again for my delay working on this, there was
no feedback. I've poked Jonas today on IRC privately, asking if he had a
comment, he said "sounds good, go ahead", and so I did.

Initially, I wanted to do what I wrote above, but in the end I just
patched the current Nautilus extension to make it work with
python-nautilus build against Python 2.7, as it will be shipped in
Debian buster.

The changes I needed to make weren't that intrusive:

- I've changed the interpreter and added "coding: utf-8" to overcome
  utf-8 errors.
- Changed some imports to make these work with Python 2.7.
- Removed type hints. (Were this backported to 2.7?)
- Removed internal calls to libmat2, replaced by two funtions to call
  the cli of mat2 (and to check the output) and to guess the mtype of a
  given file.
- Furthermore, I've removed line 5 in the following code

	class Mat2Extension(GObject.GObject, Nautilus.MenuProvider, Nautilus.LocationWidgetProvider):
    """ This class adds an item to the right-clic menu in Nautilus. """

    def __init__(self):
        super().__init__()					<-
        self.infobar_hbox = None
        self.infobar = None
        self.failed_items = list()

  as otherwise I was running into

  TypeError: super() takes at least 1 argument (0 given)

  and I was unsure what's the cause and how to fix this.

I've tested the changes quickly with some files of different types, it
seems to be working. 

I would be very happy if someone of you could review this.

I've prepared 0.7.0-2 and pushed to the branch d/0.7.0-2. The repo is
available via [1].

To ease consumption and testing, I've attached the .deb to this mail as
well, it's signed by my key. If you take this route, please note: AFAIK,
dpkg -i doesn't install recommend packages, so please install
python-nautilus manually.

Thanks in advance,
cheers,
Georg
