Exporter Error

I've been using the PG MMOKit for a while, and just noticed that Mr. Greenawalt posted the Blender source files for the MMO Kit characters. I tried exporting them as is into the DTS format, and they worked fine. However, if I add another armature, Mount4, onto the rigging it crashes the exporter with the following error:

I'm using the latest export, version .96, to export the model.

Thanks,
