Mayavi-1.5 didn't work on my system:
Traceback (most recent call last):
  File "/usr/bin/mayavi", line 317, in <module>
    app = MayaViTkGUI (r)
  File "/usr/lib/python2.5/site-packages/mayavi/Main.py", line 1009, in __init__
    self.renwin = Misc.RenderWindow.RenderWindow (self.renwin_frame)
  File "/usr/lib/python2.5/site-packages/mayavi/Misc/RenderWindow.py", line 89, in __init__

  File "/usr/lib/python2.5/site-packages/vtk/tk/vtkLoadPythonTkWidgets.py", line 54, in vtkLoadPythonTkWidgets
    if len(path) > 0 and path[0] == '{' and path[-1] == '}':
TypeError: object of type '_tkinter.Tcl_Obj' has no len()

Some googling suggested a fix to tell Tkinter not to use objects.  Will attach a patch.

Also, there was a typo in the installed desktop file: the title referred to mayavi2, I changed it to refer to mayavi1 instead.
