Thanks. I wish I understood :) Is this possible in pygtk at all?

I have just found out, that if I use "user data" column in glade, the
object is passed, but not as a (last) user_data argument, but a widget
argument. Is this the bug you meant?

I mean, if I have a cellrenderertoggle callback like
def toggled(self, cell, path):

The cell argument would not hold a cellrenderer that fired the signal,
but actually the object I defined as user data in glade.

Now I wonder, if this is gtkbuilder or pygtk issue.
