Removed my question…
Apparently, this has been fixed in 4.1.0.23 EA! Well, at least nemo is not in the file, and line 133 is different 
Could someone test the spoofing and report this in 4.1.0 release notes? I don’t plan to do it (for now).
Edit: And the corresponding change low message is:
aliendalvik-configs
[alien-aliendalvik-configs] Fix an issue where nemo is used instead of ALIEN_USER.In my case, I’m still having the same issue, even with a fresh flashed XA2 running 4.1.0.24. The symlink fix did the trick too, so I’m guessing either it was reverted or a similar issue still exists.
And it was not just the restart of the Android runtime that did it? Try removing the symlink and restarting, and see if the problem comes back.
