Hi Tom, I think your obj file is invalid, as the faces all reference normal "0" and 1> no normals are provided 2> normal indices start at 1 (according to wikipedia <https://en.wikipedia.org/wiki/Wavefront_.obj_file#Face_elements>)
if I reduce your obj file to just the first face (removing material and all but vertex/texcoord 0-1-2) ( attached ) I get the same crash with osgconv DataFace1.obj removing the /0 (normal ref) three times fixes the problem - same works for the large file (with textures working) Laurens.
