This is a deliberate change. It is documented - but I'll expand the
documentation to mention the datetime types explicitly. Use toPyObject() to
get the Python datetime instances back.

If you want the old behaviour then convert the Python types to their Qt
equivalents before converting to QVariant - and that will work Ok with
earlier versions as well.
