I don't know if there is a simpler way to do what you want but I would
imagine that every time one of the properties is set it takes precedence.
Anyway, you could use gtk_tree_view_column_set_cell_data_func() to
manually set the appropriate property. I'm not very used to do this in
Python, so it might not be the cleanest possible (like I don't know if
set_property() is the wait to go), but it works:
...
col = Gtk.TreeViewColumn("Image", renderer)
def cell_data(col, cell, model, iter, data=None):
name, pix = model.get(iter, 0, 1)
if pix is not None:
cell.set_property('pixbuf', pix)
else:
cell.set_property('icon-name', name)
col.set_cell_data_func(renderer, cell_data)
...
