activation_energies throw errors

What steps will reproduce the problem?
1. an attempt to output activation energies using the python interface fails.

import cantera as ct
gas = ct.Solution('h2o2.cti')
print(gas.activation_energies)

What is the expected output? What do you see instead?

expected output are activation energies (defined as property in kinetics.pyx)

the error message is:
  File "kinetics.pyx", line 203, in cantera._cantera.Kinetics.activation_energies.__get__ (cantera/_cantera.cpp:21979)
  File "kinetics.pyx", line 15, in cantera._cantera.get_reaction_array (cantera/_cantera.cpp:19257)
RuntimeError:
