xml menu pygtk

[Seb]

I'm trying to construct a menu from an xml file. However my recursive
algorithm isn't doing what I want it too. I've been starring at this
for too long. Any help appreciated :)

I get the following error but the problem is more of a logical nature.
./gnomeAppletMenu.py:40: GtkWarning: gtk_menu_shell_insert: assertion
`GTK_IS_MENU_ITEM (child)' failed
  menu_bar.append(menu)

I'm pretty sure I fuck up around line 27-30

xml file:
http://pastie.org/480045

python code:

best regards,
Seb
