Hi,

I'm running ros latest on the PR2 (ros core version 9752). I run into the following error when I try to do a rostopic list:

saip@pr1000:~/ros_sandbox/versioned_latest/ros$ rostopic list
Traceback (most recent call last):

    raise Fault(**self._stack[0])
xmlrpclib.Fault: <Fault 1: '<type \'exceptions.Exception\'>:method "getTopicTypes" is not supported'>

I haven't really looked into what is causing this. Any pointers ?

Thanks,
Sai
