[Bernhard Thiel]

Package: mayavi2
Version: 4.4.3-2.2
Severity: normal

Dear Maintainer,

   In the mayavi2 package some files from tvtk.pyface seem to be missing (they are present at github).
   In particular, trying to import mlab gives the following traceback 

  >>> from mayavi import mlab
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "/usr/lib/python2.7/dist-packages/mayavi/mlab.py", line 27, in <module>
      from mayavi.tools.camera import view, roll, yaw, pitch, move

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