Bug#535581: bibtool: segmentation fault in case of error

[Vincent Lefevre <vincent@vinc17.org>]

Package: bibtool
Version: 2.48alpha.2-4
Severity: normal

I get a segmentation fault on the following example.

biblio.bib is:

@article{aglp:05,
 author = {}
}

$ bibtool -q -- 'select={aglp:05 "aglp:05"}' biblio.bib
zsh: segmentation fault (core dumped)  bibtool -q -- 'select={aglp:05 "aglp:05"}' biblio.bib

In case of syntax error, bibtool should output an error message,
not segfault.
