There's a simple solution to the riddle:

It's a bug (or undocumented limitation) in PoseRay.

The official syntax of the face_indices block is as follows:

   face_indices {
     number_of_faces,
     <index_a, index_b, index_c> [,texture_index [,
       texture_index, texture_index]],
     <index_d, index_e, index_f> [,texture_index [,
       texture_index, texture_index]],
     ...
   }

Apparently PoseRay stumbles over the optional texture indices.
