Blendigo and LuxBlend - Object does not have geometry data

I am getting this error when I try to export using the LuxBlend script:

Traceback <most recent call last>:
  File "<string>", line 1380, in drawGUI
  File "<string>", line 1204, in drawCamera
  File "<string>", line 1397, in drawButtons
  File "<string>", line 863, in save_still
  File "<string>", line 779, in save_lux
  File "<string>", line 541, in exportObject
AttributeError: Object does not have geometry data

And I get this one when using Blendigo:

Traceback <most recent call last>:
  File "<string>", line 2638, in buttonEvt
  File "<string>", line 2015, in exportStill
  File "<string>", line 1986, in export
  File "<string>", line 1673, in exportObjects
  File "<string>", line 1534, in exportObject
AttributeError: Object does not have geometry data

I am using Blender 2.44, LuxBlend_0.1_alpha8, Blendigo V0.9

I’m thinking it’s something I have done or something wrong with the file since I am getting similar errors in both scripts.’

The .blend file can be downloaded here.

I’ve tried appending all objects to a new file but that doesn’t fix the problem. Any ideas?

Never used these renderers before but at a quick glance, I can see three objects with the default material (cap, gantry_plug, gantry_valve). Could it be that the exporters are choking on objects with the default (read, no) material? Just a guess.

Thank you for catching those objects, unfortunately assigning materials to them didn’t solve the export problem.
