One source causing "empty bibliography" error

Question

I'm writing a LaTeX document using biber for references. If I include the following in the .bib file:

@article{boschmassspec,
  author={Fritz Bosch},
  title={Schottky mass- and lifetime-spectrometry of unstable, stored ions},
  journal={Journal of Physics B: Atomic, Molecular and Optical Physics},
  volume={36},
  number={3},
  pages={585},
  url={http://stacks.iop.org/0953-4075/36/i=3/a=316},
  year={2003},
}

then all of my references break: even the references that worked previously will all throw reference undefined warnings and fail to properly be presented (showing the cite key instead of the number), and I get the following:

main.tex:78: LaTeX Warning: Empty bibliography on input line 78.
main.tex: LaTeX Warning: There were undefined references.
main.tex: Package biblatex Warning: Please (re)run Biber on the file:(biblatex)                main(biblatex)                and rerun LaTeX afterwards.

I am compiling the document properly (pdflatex, biber, pdflatex, pdflatex) and everything works if this one reference is omitted from the .bib file. What's wrong with it?

EDIT:

Here is a minimal example that replicates the issue:

main.tex:

\documentclass[twoside,onecolumn,11pt,a4paper]{book}
\usepackage{amsmath}
\usepackage{fancyhdr}
\usepackage{graphicx}
\usepackage{units}
\usepackage{mathtools}
\usepackage{hyperref}
\usepackage{physics}
\usepackage{amssymb}
\usepackage{parskip}
\usepackage[backend=biber,style=numeric,sorting=none]{biblatex}

\addbibresource{bibliography.bib}
\begin{document}
\cite{akberetal}

\cite{boschmassspec}

\printbibliography
\end{document}

@Comment{jabref-meta: databaseType:bibtex;}

If compiled as provided, no references work properly. If compiled without the second reference, the first one works.
