rosws info gives me error 'VcsClient' object has no attribute 'url_matches'

edit

I have been trying to use rosws to manage my workspace and .rosinstall file. I used rosws merge and rosws set to create the file, and rosws update to grab all the packages from their various repositories. now when I run rosws info I am getting all these errors that look like this:

Error processing 'rtt_geometry' : 'VcsClient' object has no attribute 'url_matches'

The python stack trace looks like:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/rosinstall-0.6.19-py2.7.egg/rosinstall/common.py", line 252, in run
    result_dict = self.worker.do_work()
  File "/usr/local/lib/python2.7/dist-packages/rosinstall-0.6.19-py2.7.egg/rosinstall/multiproject_cmd.py", line 373, in do_work
    path_spec = self.element.get_versioned_path_spec()
  File "/usr/local/lib/python2.7/dist-packages/rosinstall-0.6.19-py2.7.egg/rosinstall/config_elements.py", line 378, in get_versioned_path_spec
    if self._get_vcsc().url_matches(curr_uri, uri):
AttributeError: 'VcsClient' object has no attribute 'url_matches'

and my .rosinstall file looks like:

# THIS IS A FILE WHICH IS MODIFIED BY rosinstall
# IT IS UNLIKELY YOU WANT TO EDIT THIS FILE BY HAND,
# UNLESS FOR REMOVING ENTRIES.
# IF YOU WANT TO CHANGE THE ROS ENVIRONMENT VARIABLES
# USE THE rosinstall TOOL INSTEAD.
# IF YOU CHANGE IT, USE rosinstall FOR THE CHANGES TO TAKE EFFECT
