Windows 10 x64, Nvidia gtx970
Broken: 2.76.2 f337fea
Short description of error
When I try to move some faces of a mesh along Z normal axis using "bpy.ops.transform.translate(value=(0, 0, 10), constraint_axis=(False, False, True), constraint_orientation='NORMAL')" give a wrong result.
As show in the image, it doesn't work as expected (Icosphere.001 is edited by modeling by hand with same Z distance)
Exact steps for others to reproduce the error
