[ros-users] runid incorrect in roslaunch

     I am using the cturtle Ubuntu repositories for Lucid. When I run
roscore, if I start a roslaunch instance in another terminal, it fails with
"run_id on parameter server does not match declared run_id:
b6c96aa0-aa11-11df-96c8-001d92f61800 vs c59dc274-aa11-11df-8038-001d92f61800".
If I manually specify the runid, it works fine. ROS_IP is empty, and
ROS_MASTER_URI is "http://localhost:11311". Everything works fine, however,
if I do not start roscore manually and I let it start with roslaunch. What
is wrong? In addition, roswtf and other utilities cannot connect to the
master.
