Good afternoon,
I have a problem with org-bibtex function org-bibtex-read if I have an
empty field in a bibitem like this:
@article(test,
description = "")
In this case the "aref" gives an exception. I would like to suggest
the attached following fix.
With kind regards,
Stefan

Subject: [PATCH] [PATCH] Org-bibtex: checking string length in org-bibtex-read
before using aref
If a field in a bibtex entry is empty:
@article(test,
description = "")
the function org-bibtex-read throws an exception because of
using aref on this empty string.
The solution is to check the length of the string before.
TINY CHANGE.
