I am getting this message while running warehouseviewer on my dynamixelarm.

"Setting quaternion with all zeros"

In electric is was Ok. But now I am using Fuerte and ubuntu 12.04. I am customized my planningscenewarehouseviewer file to work with my robot. Whenever I make this option "usemonitor"=/true from false, the error is not showing, but the arm is not showing any kind of interactive marker or PSV marker. Can anybody suggest me how can i overcome this error??/

I am also unable to run my arm_navigation.launch file because of the smae error.
