You're right, it's fixed in the latest builds.
I didn't found the fix before report :(
Thanks !

@Bastien Montagne (mont29) Apparently, the "relocate bug" is not in the 2.79 release but in the 2.78a.
Should I report it nonetheless ?

Hi,
I've tried to use the bpy.ops.wm.lib_relocate but I've got an issue with proxy relinking (I know you're in love with proxies Bastien :) ).
I've also tried with the bpy.ops.outliner.relocate in the outliner through the interface and the same error appears.
Result : the armature proxy become an empty.

Can I call the relocate operator from a python file ? I can't see any parameters with it. Or maybe bpy.ops.wm.lib_relocate can do the job ?

Ok Bastien,
Thanks :)

Hi,
The issue is here since blender 2.76a I think.
2.75a does not have it.

Hi,
I'm not expecting other_lib.blend to be removed but the second Suzanne (from lib_v01.blend) to be linked to lib_v02.blend. And this is not happening. After save reopen, for blender, the second Suzanne is linked to other_lib.blend (but Suzanne has never be part of it).
Did you try the steps to reproduce this bug ?

Ok, now i'm sad :(
Thanks for the info @colin (col-one) ! :)

Hi all !

Hi Sybren,

I think I found an issue with alembic export from blender.

@Joshua Leung (aligorith) : thanks for your answer Joshua (fast again !). I'll give it a try !

@Joshua Leung (aligorith) : thanks for your (quick ;)) answer. I did what you propose but no success again (no drivers submenu in right-clic on an attribute). Maybe this patch depends on another ?

Hi Joshua,
This feature is very interesting...
Is there a way to patch the tags/v2.77 sources with this (I'm actually trying but no success) ?

My tiny little patch (please don't laugh :) ):
