Hi Robert,
The stack trace is:
Code:

& nodeCenter={...}, osg::Quat & nodeRotation={...}) Zeile 171 + 0x12 Bytes
C++
It is caused in NodeTrackerManipulator::computeNodeCenterAndRotation(..):
Code:
nodeCenter = osg::Vec3d(nodePath.back()->getBound().center())*localToWorld;
It Crashes because nodePath is empty, so nodePath.back does not work.
Where is the best place to ensure that nodepath is not empty?
Thank you!
Cheers,
Torben
