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)

This was actually reported earlier, but closed as invalid:

It might be platform-specific.

I tried this and link option is respect as it is from running the operator directly.

Could you upload sample blend files which fail?

Also possible (but unlikely) a bug for ms-windows, tested on 64bit Linux.

Not being able to make local looks like a real bug though, checking on that
correction - its not implemented. id_make_local

Note that using bpy.ops.wm.link_append from python is quite limited, we have an API for linking which lets you inspect data in the blend file.

It is indeed a Windows problem, it occurs if a Blender path with slashes is used:

  # Fails to append

    bpy.ops.wm.link_append(filepath="//Scene", directory="D:/append.blend/Scene/", filename="Scene", link=False)

  # Appends successfully

    bpy.ops.wm.link_append(filepath="//Scene", directory="D:\\append.blend/Scene/", filename="Scene", link=False)

A standard Windows path with backslashes works.

This should be made to work (or at least give some error on invalid args),
but since theres already a python api for this and it only fails when called with incorrect args, Id postpone any changes here until after 2.70
