Hum, on a "normal" Linux file system only the root user can change the immutible attribute on a file.
Running on 4.2.3 I have just removed the immutible attribute as an ordinary user if I am the owner of the file.
I would suggest that this is a bug as the manual page for mmchattr does not mention this.
