Short description of error

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

I am using Blender Git Rev 2013-12-19-09-57-44-01745d3 on Linux Fedora
19.

I notice that suzanne when first added to the 3D Viewport is Rotated
on the X Axis by 90 degrees. This causes problems with Dupliverts
as demonstrated in the Blender Wiki. The monkies are all oriented
strangely. If you apply the rotation, then everything fixes itself.

It could be a good idea to make it so that when suzanne is first added
to the 3D Viewport (in the upright position) that rotation values all
be set to 0. When you do that the Dupli-verts example shown works
in a more expected way as shown in the wiki. Which you can see by
applying the rotation on the suzanne. Also it would be more in
keeping with the rest of the objects which don't appear to have rotation
applied.

I uploaded a test blend file showing the issue and my system-info.txt file

Looking into this, its in fact intentional.

If you want to control the orientation of an object you need to use the track axis settings.

Hi Campbell, I know about the Relations Extra panel but if you use it with rotation at 90 of suzanne you still don't get the duplicated objects aligned as expected.

More specifically the duli-vert setup was to show that odd default rotation of suzanne has an effect on a stuff mentioned in the wiki. This bug should really have been titled wrong default rotation values for suzanne.

I had a patch which made the transformation apply relatively (loc/rot/scale), which addresses this report.

But I didnt end up committing it because it changes existing behavior quite a lot. (checked the tracker search but didnt manage to find so far)
