[osg-users] Loading textured meshes (obj+mtl) leads to crash in osg 3.4.1

[Robert Osfield]

I have looked at the model with the 3.6 branch and get the crash and concur 
with Luarens - the model is broken, it has normal indices assigned to the 
faces but no normal array.  The crash occurs because the OSG's obj plugin 
is assuming that if normal indices are provided they are valid normal 
indices.

Where did this model come from?
