Curve Deform with Bezier Curves works good until shape keys are added, then the mesh twists around the curve.

Here's the thread on Blender Artist for more info:

Approved, assigning to Sergey.

Sergey, this fails in simple cases.
* add default Bezier curve.
* tilt entire curve (approx 90deg)
* exit edit mode
* add a shape key
* enter editmode
* exit editmode *** curve tilt changed ***

Looks to like like in some places the tilt is intended to be a relative value to the basis, others not.
