AttributeError: JointStatePublisher instance has no attribute 'source_update_cb' #36

Getting this error on Ubuntu 16.04 and ROS Kinetic: [ERROR] [1582565767.970762]: bad callback: <bound method JointStatePublisher.source_cb of <joint_state_publisher.JointStatePublisher instance at 0x7ff0c19dc5a8>> Traceback (most recent call last): File "/opt/ros/kinetic/lib/python2.7/dist-packages/rospy/topics.py", line 750, in _invoke_callback cb(msg) File "/opt/ros/kinetic/lib/python2.7/dist-packages/joint_state_publisher/__init__.py", line 202, in source_cb if self.source_update_cb is not None: AttributeError: JointStatePublisher instance has no attribute 'source_update_cb'

Why source_update_cb is set to None aftrer subscribers are created? Shouldn't this variable be initialized before creating subscribers?
