Package: biber
Version: 2.17-2
Severity: normal
Dear Maintainer,
I updated biber to 2.17, and now I am getting many warnings (thousands of them
for large bib files, which significantly slows down biber itself) from files
that were clean before. The warnings all look like this:
```
Use of uninitialized value $opt in hash element at
/usr/share/perl5/Biber/Config.pm line 977.
Use of uninitialized value within %Biber::Config::CONFIG_OPTSCOPE_BIBLATEX in
hash dereference at /usr/share/perl5/Biber/Config.pm line 977.
```
Sometimes the line numbers are different (I have seen 967, 972, 977).
*Any* use of biber causes that warning for me, so here is an arbitrary example:
```
\documentclass[10pt,a4paper]{article}
\usepackage[backend=biber]{biblatex}
\addbibresource{bib.bib}
\begin{document}
\fullcite{iris}
\end{document}
```
With `bib.bib` being
```
@inproceedings{iris,
author = {Ralf Jung and
David Swasey and
Filip Sieczkowski and
Kasper Svendsen and
Aaron Turon and
Lars Birkedal and
Derek Dreyer},
title = {{Iris}: Monoids and Invariants as an Orthogonal Basis for
Concurrent
Reasoning},
booktitle = {{POPL}},
year = {2015},
doi = {10.1145/2676726.2676980},
}
```
I reported this upstream at https://github.com/plk/biber/issues/403, but the
maintainer suggested this might be a packaging issues since they could not
reproduce the problem.
Kind regards,
Ralf
