Dear all,

When I use RVIZ to display laser scan data from a hokuyo laser range finder 
(UTM30LX), after some time, RVIZ crashes with the following.

/opt/ros/cturtle/ros/bin/rosrun: line 35:  2515 Segmentation fault      $exepath 
"$@"

Any help will be greatly appreciated to solve the problem.

Thank you in advance
Peshala
