bibtex-validate-globally

[Greg Bognar]

I have a question about the funtion bibtex-validate-globally.
According to its description, it should check for duplicate keys in
the variable bibtex-files.  By default (in bibtex.el), this variable
is set to nil, so the function does not do anything.  However, if I
set it to bibtex-file-path, whose value is given by (correctly) the
variable BIBINPUTS, it gives me a Wrong type argument: listp, [value
of bibtex-file-path].  So it seems that even though BibTeX sees my
dedicated directory of bibliography files, bibtex-validate-globally
does not work.

It would be nice if it did work, since I have a number of bibliography
databases in that directory, and bibtex-validate-globally could be
very useful to find duplicate keys.

What am I doing wrong?

Thanks,
Greg
