[maemo-developers] Gtk error from ComboBoxEntry

[From: Jeffrey Barish]

I am getting the error message

AttributeError: 'gtk.ComboBoxEntry' object has no attribute 'get_cells'

I suppose that this error must result from a maemo abridgement because the
gtk documentation describes this method (in gtk.CellLayout).  A
ComboBoxEntry installs the renderer automatically, so how am I supposed to
get it so that I can change its attributes?
