**System Information**
Windows 7
**Blender Version**
Broken: 2.69 (and at least 2.67, 2.65, 2.57)
**Short description of error**
`bpy.ops.wm.link_append()` called from script ignores the link-argument and always links. If you try it with a scene, you can't even make it local in UI afterwards. It works fine via //File / Link/Append//
**Exact steps for others to reproduce the error**
Example code:
import bpy
bpy.ops.wm.link_append(
filepath= "//slave.blend",
filename= "Scene",
directory= "C:/Program Files/Blender Foundation/slave.blend/Scene/",
link=False,
relative_path=True)
