Errors in exported BibTeX file when protecting capitalization

[roby1984]

Version: 1.1.5

Description: When the "protect capitalization" flag is active, the Date field is surrounded by double brackets in the exported BibTeX file, making LaTeX hang when a publication with the same year and the same authors is cited in the LaTeX document.
Corresponding LaTeX error:
! Missing = inserted for \ifnum.
<to be read again>

I would suggest protecting only the text fields (title, author and journal, etc.). The braces around the doi field also mess up the output of my bibtexstyle, for example, making the links unresolvable.

Braces around most fields is overzealous. Many fields do not require double braces at all, in particular fields with integer numbers.

Inspired by this thread which describes a very similar problem: http://tex.stackexchange.com/questions/10587/latex-error-when-citing-paper-with-similar-authors-and-same-year-using-natbib , I created a small patch (attached) to only protect titles when the "protect capitalization" option is used. I expect this patch will solve the bug described.

Oops, I screwed up my patch in #2. The patch attached to this should be correct.

Is it not enough to not double brace numerical fields such as year, volume, etc.?
I have commited this in my development branch as http://bazaar.launchpad.net/~referencer-devs/referencer/shiyee_andrease_changes/revision/856

@Mads: do you consider mixed fields, such as the 'doi' field as well?

[Mads Chr. Olesen (shiyee)]

@bartgenuit: In what I commited the doi is not getting double brackets.
