System Information
Win7 x64, GTX 760

Blender Version
Broken: in master
Worked: always was this way AFAIR

Short description of error
Manipulator handles and transform axis are always drawn based on the position of the selected vertexes in a KeyBlock and not at the evaluated mix position!

Exact steps for others to reproduce the error

Open singvert.blend
Observe the manipulator being drawn in the wrong place
Try changing the vertex's position and enable axis snapping (hit G and X, Y, or Z or drag the manipulator's axis)
Observe the axis mark being drawn in the wrong place

Located what's wrong: calc_manipulator_stats in transform_manipulator.c uses just the data from EditMesh, which is going to be noticeable in shape keys. It appears I'll need to bring in DerivedMesh data just after the Shape Keys modifier

This is known limitation, not just with shape-keys, but with all modifiers.

Even though the vertices draw at a different place, you are still editing the values at their source location, where the manipulator draws too.
