[ros-users] Stage with Pioneer

[Eliot Beckham]

Output is as follows:

[FATAL] [1320680361.313360376]: number of position models and laser models
must be equal in the world file.
[FATAL] [1320680361.313471845]: BREAKPOINT HIT
    file =
/tmp/buildd/ros-diamondback-simulator-stage-1.2.5/debian/ros-diamondback-simulator-stage/opt/ros/diamondback/stacks/simulator_stage/stage/src/stageros.cpp
    line=207

Line 207 in the current stageros.cpp file does not contain the code to
provide this output.
