If you search for 'arrow' in plug-ins/python/*.c there are only few 
occurences. One of them is PyDia_get_Arrow; note this missing PyDia_set_Arrow.

the only way to modify DiaObject properties is through the properties or by 
calling some member functions.

objects of that type ..."

The Arrow type is not a DiaObject.
