paho_mqtt/packet/base.rb:126 - Invalid packet type identifier: 0

Another frequent exception I get is:

vendor/cache/tether-mqtt-bcf38e610db8/vendor/paho.mqtt.ruby-master/lib/paho_mqtt/packet/base.rb:126 in create_from_header

vendor/cache/tether-mqtt-bcf38e610db8/vendor/paho.mqtt.ruby-master/lib/paho_mqtt/client.rb:133 in block in daemon_mode

Any ideas what this is and how to fix?
