[O] bug in org-create-link?

[mirko]

The following is with release_8.2.5h-649-g2ae5cf.

I get an error when creating a link to a file.

The error originates in code
       (cond ((equal desc "NONE") (setq desc nil))
             ((string-match org-bracket-link-analytic-regexp desc)
               ...)
            ...)

I think the error is due to a quirk in my setup, which I was not able to
isolate yet.  I do not get this error with all files, only some of them.

I wonder whether there is some inconsistency in the code. In the lines
immediately preceding the cond statement, desc is set to NIL:
       (setq link (or link cpltxt)
             desc (or desc cpltxt))

Should desc be set to "NONE" by default like so:
       (setq link (or link cpltxt)
             desc (or desc cpltxt "NONE"))

Then the cond statement would be able to handle it.  I hope someone can
answer that question quicker than for me to figure out the full logic of the
code.

Thanks,

Mirko
