The recommended practice for that is _not_ to set group_cipher yourself
and just rely on wpa_config_set_network_defaults() doing the correct
thing. I don't think you were calling that function in your code, but it
might be best to start with that and then update just the fields you
need to change. Not that this makes much difference for 0.5.x branch,
but in general, that would be the safest way to avoid hitting similar
issues with whatever new parameters are added in the future.
