Comment 4 for bug 1244670

Thanks. The file seems to be located in /usr/share/gufw/gufw/view/utilsview.py

After replace:

$ gufw

(gufw.py:2584): Gtk-CRITICAL **: gtk_list_store_get_column_type: assertion 'index < priv->n_columns' failed
Traceback (most recent call last):
  File "/usr/share/gufw/gufw/gufw.py", line 34, in <module>
    app = Gufw(fw_frontend)

    self._set_initial_values()

    return GObject.Value(self.get_column_type(column), value)

    self.init(value_type)
TypeError: Must be gobject.GType, not gobject.GType

Then I commented line 121 out - it looks like a bug anyway :)
#self.rules_model.set_value(iter_row, 13, row) # number

And tried again. This time it run ok, see the screenshot.

To me it looks better now, but still some pixels in the very end of the widow (20 or so pixles) are still not visible.

For refernce gufw.cfg

[GufwConfiguration]
profile = Home
windowwidth = 371
windowheight = 560
expandrules = yes
expandlog = yes
expandlistening = yes

Hope this helps.
