The error is in editperson.py line 1063.  As it says: takes exactly 0
arguments (1 given)
So, passing the parent argument is wrong. You should look at the
documentation of the class: Gtk.MessageDialog, so
http://developer.gnome.org/gtk3/stable/GtkMessageDialog.html
The init of us, is the C new method:
http://developer.gnome.org/gtk3/stable/GtkMessageDialog.html#gtk-message-dialog-new

So from this, one could deduce that parent will be a named argument, and
needs to be passed as
parent=parent

It is interesting to check if there are no specific overrides, as this
could override how the arguments must be passed. This is needed here, as
the new method above ends with ... and in python that is not defined. So go
to the overrides:
http://git.gnome.org/browse/pygobject/tree/gi/overrides/Gtk.py

and search for MessageDialog. You find:

class MessageDialog(Gtk.MessageDialog, Dialog):
    def __init__(self,
                 parent=None,
                 flags=0,
                 message_type=Gtk.MessageType.INFO,
                 buttons=Gtk.ButtonsType.NONE,
                 message_format=None,
                 **kwds):

So indeed, parent is named argument.
Conclusion:

 class GenderDialog(Gtk.**MessageDialog):
>     def __init__(self, parent=None):
>         GObject.GObject.__init__(self,
>                                 parent,
>                                 flags=Gtk.DialogFlags.MODAL,
>                                 type=Gtk.MessageType.QUESTION,
>                                    )
>

should be instead:

        GObject.GObject.__init__(self,
                                parent=parent,
                                flags=Gtk.DialogFlags.MODAL,
                                type=Gtk.MessageType.QUESTION,
                                   )

This is wrong. In the trace python prints one line, while line 1063 are 5
lines  of code, the error can be in all 5, not only in the one line printed.

Yes, this is warning where I know where it happens, so i added a print:
GRAMPS GTK3: a g_value_get_object warning:

You can grep the code and find that line. I don't know how to avoid the
warning message, all looks ok to me.
Other lines of output appear, and are related to the interface theme you
choose. Eg, if I choose Rayleigh in KDE, I have ugly Gramps with little
warnings printed, if I choose Qt-GTK, I have many warnings. As you are on
Gnome, perhaps change some themes and let us know which one gives little
warnings.
