Hi folks,

I am running latest ROS and have a strange problem that shows up when running this little snippet of code:

#! /usr/bin/env python

import roslib; roslib.load_manifest('wubble_actions')
import rospy
import tf

if __name__ == '__main__':
    rospy.init_node('tf_test', anonymous=True)
    tf = tf.TransformListener()
    rospy.spin()

After running this node I get the following error:

terminate called after throwing an instance of 'ros::TimeNotInitializedException'
  what():  Cannot use ros::Time before calling ros::init
[test_tf-11] process has died [pid 15907, exit code -6].
log files: /home/anton/.ros/log/6e6c07b8-7389-11df-9736-0026b0e3798c/test_tf-11*.log

Does anybody have an idea what might be wrong here?

Thanks,
Anton
