%%%--- Operating System, Graphics card ---

renderer: 'GeForce GTX 560 Ti/PCIe/SSE2'

- Blender version with error, and version that worked ---

version 2.69 (sub 0), revision b'60761'. b'Release'
build date: b'2013-10-15', b'00:14:56'
platform: b'Windows:64bit'
binary path: 'C:\Blender\BlenderDEV\blender.exe'

- Short description of error ---

Got a wrong transform while modeling. Took me awhile to figure it out. Only happens with the following combination :

Object has a rotation transform on it (rotation is not zeroed)
(While in Edit mode)
Transform orientation is in Normal mode
Pivot mode is set to Individual origins
Only one vertex is selected.

Pressing G+ZZ or grabbing the Z axis on the manipulator to move the vertex along it's normal direction will fail to move the vertex using it's correct (post transform worldspace) normal. It seems to use the pre transformed normal dir instead (as if the model was not rotated).

This only happens with a single vertex selected. Selecting a second vertex results in the correct direction (average of WS normals).
This problem does not occur with single edge or single face selections, i imagine because those elements are averaging multiple vertex normals.

Current workaround is applying rotation transform, though this is not always desirable.

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

1 - Open new scene and add a suzanne model.
2 - Press RR and apply an arbitrary rotation (rotation is not (0,0,0)) to suzanne. so that object space normals and world space normals should differ.
3 - Go into edit mode
4 - Set Pivot mode to Individual Origins
5 - Set Transform Orientation to Normal
6 - Select a single vertex
7 - Attempt to move along normal direction (G+ZZ or grab manipulator Z)

Although the manipulator is properly aligned, the vertex will not move along the vertice's world Z axis%%%

%%%upon further investigation, it seems "individual origins" pivot mode + normal dir is not functioning properly at all in 2.69.2
Multiple element selections result in averaged normal direction movement, not along individual origins.

I've verified the same actions in BL 2.68 release, and the behavior is functioning properly there.%%%

%%%Confirmed, this doesn't look right.
@Campbell: Can you check this? I think you've worked in this area recently. Attached a simple test file, just do g+zz on the selected vertex.%%%

Just tried daily build 2013-12-03 05:14 hash ab49437
would the fix be present in this build?

Although what made me originally submit this bug seems fixed, the overall functionality still seems flawed (as mentionned in subsequent comment)

Moving multiple vertices along their individual origins worked great in BL 2.68a release. Now they seem to move in averaged groups depending on whether or not they are connected (share a loop?). Is this by design? Was this changed to help moving faces using individual origins?

If so, could this method be employed when in face mode, but keep the 2.68a behavior when in vertex mode?

thanks
