NoMethodError: undefined method `in_transaction?' for nil:NilClass

In latest master, I get this exception from time to time:

#<Thread:0x00000000430f3348@/data/deployer/current/vendor/cache/xanview-mqtt-92d6cd687553/vendor/paho.mqtt.ruby-master/lib/paho_mqtt/client.rb:198 run> terminated with exception (report_on_exception is true):

NoMethodError: undefined method `in_transaction?' for nil:NilClass

Any ideas?

Thank you for waiting.
The reason seems to be that the client try to read from a closed socket, raising a not handled exception. I am keeping investigation, and I would try to write a fix soon.

Any update on this one? - this is still happening occasionally.
