From Paul Martz, "When exporting a DrawArrays PrimitiveSet, the DAE plugin computes an incorrect nbVerticesPerPoly if the first index is not zero. The issue can be reproduced easily with:

Browse Source 
osgconv cessna.osg cessna.dae
 
Examination of the resulting .dae file reveals several out-of-range tristrip indices; viewing the .dae file in osgviewer causes a crash when OSG tries to lookup those indices.
 
Attached resolves this issue."
