Upload of rigged mesh crashes viewer

[canny]

1. Obtain a dae of a mesh body from Signature. This will have been exported out of Blender from Avastar plug in. ( This riged mesh does not crash the viewer on upload)

2. Run said dae though Cathy Foils Mayastar plug in for Maya. (there's a process).

3. Log into Second Life and in the build menu upload mesh.

4. Select the file on your hard drive and click the ok button

5. Watch as the view crashes and didn't even show the mesh in the preview.

Reproduced the crash using the TestObject.dae mentioned in Canny.
Will fix in the GLTF Import repo.

My repro scenario is different:

1. The model appears in the preview (may need to uncheck "Skin weights");
2. Clicking "Calculate weights & fee" results in the crash.
