It's possible to have a group in bpy.data.groups that has no objects. This causes the code that finds the best source scene to fail in export_fbx_bin.py However, export_fbx.py avoids this problem because it doesn't attempt to find the best source scene.

Unless there's an obscure reason to export empty groups, I would suggest changing the following lines in both export_fbx_bin.py and export_fbx.py from:

      if batch_mode == 'GROUP':
          data_seq = bpy.data.groups
      else:
          data_seq = bpy.data.scenes

to:

      if batch_mode == 'GROUP':
          data_seq = [group for group in bpy.data.groups if len(group.objects) > 0]
      else:
          data_seq = bpy.data.scenes
