It's quite odd, but I know the reason why it's happening. I wrote the
class as:

class CTree(gtk.GtkCTree, CList):
        pass

where CList is

class CList(gtk.GtkCList):
        pass

Because I wanted to take advantage of the features implemented in my
CList. This is broken inheritance, as I see it, since we have:

GtkCList -> GtkCTree -> CTree
     \                  /
       ----my CList----

I've been thinking of how to fix it, and the only way I see it is
providing a separate class to execute the actual extensions and call that
from my CList/CTree as a helper. Does that sound sane?

Right, but that broke when I did my inheritance foobar. Now I see why this
is complicated :)

Take care,
