%%%--- Operating System, Graphics card ---
Windows 7 64, HD 5770

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

error: 2.68a r58537

- Short description of error ---

Game Engine
Logic-Bricks: EditObject-Actuator adds objects with illogical scaling behaviour.

For example, a gun parented on a armature will fire projectiles with the same scaling of the armature,
and not with the scaling of the gun.

That means, Add-objects will take over the scale of its "highest parent" and ignore its emitter-object.
Please see my attached file for another example.

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

I have attached a file.

Setup for emission:

Add a Cube and move it to another layer.
For Cube, set Logic-Bricks: Always>and>Motion(set a Value for X/Y/Z)
Go to original layer and add an Empty.
For Empty, set Logic-Bricks: Delay200repeat>and>EditObject(AddObject:Cube)
Start Game Engine, the Empty shots Cubes.

Problem:
6. Scale Empty and start Game Engine > bigger/smaller Emptys = bigger/smaller Cubes
7. Add another Empty2 and parent Empty to Empty2.
8. Scale Empty and start Game Engine > bigger/smaller Emptys = nothing happens to Cube.
9. Scale Empty2 and start Game Engine > now it works like in step 6.%%%

This isn't a bug, but a feature design. If you scale the uppermost parent (if you have this relationship Armature->Empty->Gun, the armature is the uppermost parent) all children are scaled. If the original scale of the empty is an Identity, then the child won't inherit any scaling.
