Public bug reported:

Running libreoffice 1:4.2.6.3-0ubuntu1 on trusty.

I put a script in ~/.config/libreoffice/4/user/Scripts/python which
imports Gtk, and on importing it freezes libreoffice with this
traceback:

gabor@mycomputer:~$ loffice
/usr/lib/python3/dist-packages/gi/module.py:178: Warning: cannot register existing type 'GtkWidget'
  g_type = info.get_g_type()
/usr/lib/python3/dist-packages/gi/module.py:178: Warning: cannot add class private field to invalid type '<invalid>'
  g_type = info.get_g_type()
/usr/lib/python3/dist-packages/gi/module.py:178: Warning: cannot add private field to invalid (non-instantiatable) type '<invalid>'

  g_type = info.get_g_type()
/usr/lib/python3/dist-packages/gi/module.py:178: Warning: cannot register existing type 'GtkBuildable'

  g_type = info.get_g_type()
/usr/lib/python3/dist-packages/gi/module.py:178: Warning: g_once_init_leave: assertion 'result != 0' failed
  g_type = info.get_g_type()

Steps to reproduce:
Put this minimal script in ~/.config/libreoffice/4/user/Scripts/python :

# -*- coding: utf-8 -*-

from gi.repository import Gtk

def HelloWorld():
	dialog = Gtk.MessageDialog(None, buttons=(Gtk.STOCK_OK, Gtk.ResponseType.OK), message_format="Hello World!")
	dialog.run()
	dialog.destroy()

Run it from Writer - Extras - Macros - Run macros (not sure about the
english names, LANGUAGE=C libreoffice doesn't change the language)

Result: Libreoffice freezes, doesn't react anymore.
