[pygtk] Increment warning level

[Alessandro Dentella]

Hi,

  After a change in my code, I receive the follwing message (alone)

./invitati.py:31: Warning: unable to set property `text' of type `gchararray' from value of type `PyObject'
  gtk.main()

 I can't really understand where it comes from. It seems I'm setting a cell
 renderer with pyobject type and I'm setting a 'text' property on it...

 Is there a way I can increment the verbosity of the warning, to understand
 which callback triggers it?

 thanks in advance
