Pygtk2 and Vte segfault

Hi list,

I'm playing with pygtk2 and the gnome terminal emulator widget vte (its
python bindings) and I stumble upon a fully reproduceable segfault.
I basically append a terminal to a container, and afterwards I need to
"move" the terminal to a different container. 
Going through the old archives of pygtk where this question has come up,
it's been stated that a remove() of the widget from the old container
and an add() on the new one should suffice. As 

I'm fairly positive that this is a vte fault, but before whining on
bugzilla about it, I wanted to know if I'm doing something fundamentally
wrong from the python side.

I attach the test-case that segfaults (note that whenever I move _any_
other widget that is not a vte terminal everything is fine).
Below is the segfault I get.

So any tips from the pygtk folks, before I stare at vte's code?

thanks,
Michele
