[pygtk] PyGobject set pixbuf value to None

[Yann Leboulanger]

Hi,

I am trying to port my application to Gobject introspection, and I am 
facing a problem. I have a TreeModel that contains a GdkPixbuf.Pixbuf in 
one of its columns. When I try to do:

model[iter][PIXBUF_COL] = None

I get a Traceback saying:

TypeError: Argument 3 does not allow None as a value

So I wonder how can I do to not show a pixbuf for this iter. I found 
this thread suggesting that it's a bug in GObject, but is that true?

Thanks in advance for your help,
