The real reason that the expanders do not appear in maemo is a very bad style design decision which 
needs to be revised.  Specifically, maemo has set the (GTK 2.6) GtkTreeView:expander-size property to 
*0*, thus deleting the expanders.

This is bad design indeed: by deleting the expanders, there is NO WAY to distinguish between leaf 
nodes in the TreeView tree and non-leaf nodes with hidden children.  You cannot tell that clicking on a 
row will expand to kids or not.  This converts TreeView into a kind of mystery meat mechanism.

In pygtk, this ugliness can be worked around by forcing a replacement style (ugh!), like this:

gtk.rc_parse_string('''style "toolkit"
{
        GtkTreeView::expander-size = 14
}

class "GtkTreeView" style "toolkit"
''')
