Strange error in Biber

Question

I am getting a strange error that I do not understand upon the compilation of the bibliography using Biber:

:2620: parser error : Premature end of data in tag section line 2218 ^ :2620: parser error : Premature end of data in tag controlfile line 2 ^

INFO - This is Biber 2.1 INFO - Logfile is 'THESE_docm.blg' INFO - Reading 'THESE_docm.bcf'

Process exited with error(s)

My bibliography do not compile and I do not understand this error - the main document compiles fine with XeLaTex - so I do not know where or what to look for. Biber compiles normally for another latex document, I tried cleaning the output files but it still does not compile. I even tried commenting the whole document.

Any clue what I could do? Here is the MWE:

\documentclass[twoside,10pt,a4paper]{report}
\usepackage{fontspec} 
\usepackage{docmute}
\usepackage{filecontents}
\usepackage[hyperref=true,
            url=true,
            doi=true,
            natbib=true,
            backref=true,
            backrefstyle=three,
            backend=biber,
            refsegment=chapter,
            citestyle=numeric-comp,
            style=chem-rsc,
            maxcitenames=5,
            date=year,
            block=none,
            maxbibnames=100]{biblatex}

Update the 29th of November 2015: It would seems that this problem no longer appear after updating the biblatex package.

Found the problem ! It came from loading the package docmute that I planned to use in the futur. All I had to do was to load docmute after biblatex and now everything compiles fine.

\usepackage{fontspec} 
\usepackage{filecontents}
\usepackage[hyperref=true,
            url=true,

            natbib=true,
            backref=true,
            backrefstyle=three,
            backend=biber,
            refsegment=chapter,
            citestyle=numeric-comp,
            style=chem-rsc,
            maxcitenames=5,
            date=year,
            block=none,
