Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

I have lots of links to specific pages in a pdf like
[[filename.pdf::24]] which works fine (with a correctly configured
org-file-apps) but when I export to latex the page number is ignored and
the includegraphics directive includes the first page. This can
obviously manually be changed using #+ATTR_LATEX: :options page=42 but
as the page number is already there it would be nice if orgmode would
automatically use that when exporting.

Good idea. Page number can be accessed with

  (org-element-property :search-option link)

However, it should be checked against "\\`[0-9]+\\'" since a search
option can also be a headline:

  [[file:test.org::*My headline]]

Also, I guess it should only apply to link to pdf files.

Do you want to provide a patch for that?

It's not. Thanks for the patch. Some comments follow.

Missing full stop.

You also need to add "TINYCHANGE" on a line below if you don't have
signed FSF papers yet.

I suggest to let-bind SEARCH-OPTION instead of calling
`org-element-property' twice. Also, it's better to use
`org-string-match-p' instead of `string-match' since you don't use
match-data anyway. Eventually, you need to check if SEARCH-OPTION is
non-nil, as (string-match REGEXP nil) throws an error.

  (let ((search-option (org-element-property :search-option link)))
    (when (and search-option
               (equal filetype "pdf")
               (org-string-match-p "\\`[0-9]+\\'" search-option)
               ...)
      ...))
