Confirmed with pygtk 2.6.3 and 2.8.0.

See ya,
Comment 1 Gustavo Carneiro 2005-09-27 20:40:25 UTC 
Not PyGTK's job to verify these constraints.
The program causes infinite recursion in gtk_box_forall.
Comment 2 Matthias Clasen 2005-09-28 04:30:38 UTC 
Not GTK+'s job either, but the job of the programmer.
Comment 3 Gustavo Carneiro 2005-09-28 09:56:56 UTC 
Indeed, PyGTK programmers are getting too spoiled ;)
Comment 4 Gustavo Noronha (kov) 2005-09-30 00:47:06 UTC 
I agree, but wouldn't it be nice if pygtk could detect this and raise an
exception? I believe raising an exception when widget != parent fails would be
pretty nice.
Comment 5 Loïc Minier 2005-10-09 11:46:40 UTC 
(And it shouldn't segfault.)
