# LaTeX error messages are broken

I always got the same error (TeX Live 2013, pdfTeX 3.1415926-2.5-1.40.14, the very most up2date version):

```(/home/meisterluk/.texlive/texmf-dist/tex/latex/glossaries/dict/glossaries-dict
ionary-English.dict) (./thesis.glsdefs) (./thesis.toc) [1{/home/meisterluk/.tex
live/texmf-var/fonts/map/pdftex/updmap/pdftex.map}] [2] [3]
Chapter 1.
(./prev_work.tex
! Missing number, treated as zero.
<to be read again>
{
l.14 the following properties~\cite{biere}
: % page 10
?```

This annoyed for like one week because I could not find the error and could not go on with my bachelor thesis. Obviously it has something to do with biblatex (because of \cite), right? I replaced all parts of the bib file, but could not find the error. Now it tried to create a MWE to find the error (to post it to SE) and removed all parts of the TeX file. Finally I found it:

```\hypersetup{
pdftitle={\@title},
pdfauthor={\@author},
pdfsubject={SAT solvers in cryptanalysis},
pdfcreator={\LaTeX},
pdfkeywords={SAT solver, hash algorithms, differential cryptanalysis},
urlcolor=[rgb]{0.2,0.2,0.2},
linkcolor=[rgb]{0.2,0.2,0.2},
citecolor=[rgb]{0.1,0.1,0.1}
baseurl={http://lukas-prokop.at/proj/bakk_iaik},
pdfview=FitV,
pdflang={en-US},
unicode,
breaklinks,
colorlinks,
bookmarks
}```

Can you see the missing comma as separator after citecolor? Yes, this is the error. `citecolor` only affects citations and `\hypersetup` does not see an error.
