MapForwardSimulator does not fail gracefully when known to have to no free parameters

import pygsti
from pygsti.modelpacks import smq1Q_XY
from pygsti.circuits import Circuit
from pygsti.baseobjs import Label
test_model = smq1Q_XY.target_model('static')
test_circuit = Circuit([Label('Gxpi2',0)], line_labels=(0,))
test_model.sim.bulk_dprobs([test_circuit])

The above yields an Array access out-of-bounds error but does not explain that it is expected to fail.
