[pygtk] Debugging Verbosity?

[Adam Tauno Williams]

Are there flags, etc... I can provide in/to a PyGTK application to
increase debugging messages?  For example, when I start my app I see a
message -

main.py:27: Warning: unable to set property `text' of type `gchararray'
from value of type `PyObject'
  gtk.main()

Which isn't terribly helpful.

When I run a certain dialog [designed in Glade, using Builder] I see a
message like -

Warning: unable to set property `text' of type `gchararray' from value
of type `PyObject'
  self.dialog.run()

What is the best way to track down where these errors/warnings are
actually coming from?
