如果文档包含 .bib 文件中没有的参考文献，texi2dvi 将永远运行

Question

如果我使用 [texlive 2012] 运行下面的示例texi2dvi (GNU Texinfo 5.2) 5381，它永远不会停止。如何避免这种情况？这有点奇怪。我以前在文件中有很多引用，但文件中还没有.bib。它仍然会创建.pdf并以粗体字母显示键。但在过去的几天里，它似乎已经发生了变化（我所做的就是将 Ubuntu 升级到 14.04）。当我使用pdflatex、bibtex、时pdflatex，我当然会得到.pdf。如果您需要更多版本号等，请告诉我。（pdflatex显示pdfTeX 3.1415926-2.4-1.40.13 (TeX Live 2012)）

\documentclass{scrartcl}
\usepackage{filecontents}

\usepackage[backend=bibtex]{biblatex}
\addbibresource{bib.bib}

\begin{document}
Just some reference: \textcite{myfoo}
\printbibliography
