Hi Willy,

you most likely first had a .rosinstall with this line:
- svn: {local-name: ros, uri: 
'https://code.ros.org/svn/ros/stacks/ros/tags/ros-1.6.0'}

and now you have changed it to this line:
- svn: {local-name: ros}

This is a lack of robustness in rosinstall. For each svn entry, a uri 
must be supplied. A better error message would be nice.

If you do not want to get updates from svn, also change the entry type 
to "other":
- other: {local-name: ros}
