Bug#839872: python-mayavi: Missing files ("No module named tvtk_scene")

[Andreas Kloeckner]

Package: python-mayavi
Version: 4.4.3-2.2
Severity: normal

Dear Maintainer,

Using the package, I found that much of tvtk seems to be missing:

Traceback (most recent call last):

    main()
  File "local-expand.py", line 283, in main

    from tvtk.pyface.tvtk_scene import TVTKScene
ImportError: No module named tvtk_scene

Thanks,
