--- Operating System, Graphics card ---
Ubuntu 13.04 x64
Renderer: ATI Radeon HD 4770
Vendor: ATI Technologies Inc.
Version: 3.3.11672 Compatibility Profile Context


--- Blender version with error, and version that worked ---
Issue appearing: Buildbot Linux x64 Revision 58250
No Issue: 2.67b release


--- Short description of error ---
Simple deform modifier doesn't recalculate normals, so if I have Shrinkwrap modifier right after Simple deform, projection would go wrong.


--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
See for attached blend file.
Left - Simple deform not recalculating normals
Right - SubD and Simple deform modifiers are applied

If you open it in 2.67 release, you wont notice any differences between Left and Right case.
