            Bug ID: 748852
           Summary: Override changes Gst.ElementFactory.make arguments
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-python
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: otsaloma at iki.fi
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

I have gotten bug reports in Gaupol that the following code doesn't work if the
user has gst-python installed (see #748813).

    Gst.ElementFactory.make("textoverlay", name=None)

Your override changes both argument names, thus breaking keyword argument use,
which I tend to often prefer since it makes the code self-documenting. To my
knowledge, keyword argument use should be fine with PyGObject, i.e. they're
part of the API, see e.g. gtk-demo.py [1].

Gaupol doesn't depend on gst-python and I was surprised to find out such a
thing still exists, but there was no information at the web site [2]. So, if I
may ask, what is this gst-python?, why is it needed?  and is it intended that
you override function signatures or just an accident? Can I as an application
developer expect that things should work the same for users with and without
gst-python?
