System Information
Operating system and graphics card
Wind7 64bit, GeForce GTX

Blender Version
Broken: example: 2.70, 2.72a.73f5a47

Short description of error
Using an armature to deform a mesh and using the mesh to deform a curve with the mesh deform modifier gets displayed correctly in the viewport. But as soon as you switch to rendered viewport or render the image the mesh deform modifier gets ignored.

Exact steps for others to reproduce the error

Extrude the default cube so it forms an L shape
Create an armature that follows the shape
Parent the cube to the armature with automatic weights
Create a bezièr curve
Manipulate so it is inside the L
Set extrude of the curve > 0, so it gets rendered.
Use the cube as the target object for a mesh deform modifier on the curve
Bind
deform the armature (gets shown correctly in the VP)
Render (Mesh deform is ignored)MeshDeformBug.blend

Confirmed. Also:

Does not affect meshes (i.e. if I bind a mesh in place of curve in given file, it works as expected).
Does not affect 'basic bindings' (i.e. a curve bound to a mesh, even if the mesh is further deformed through e.g. SimpleDeform modifier, works as expected).

So, seems to be a conjunction between bound curve and armature-deformed binder... :/ Did not dig further.
