Re: Issue with internal links

[Tim Cross <theophilusx@gmail.com>]

Hi Marvin,

while what you have done may have fixed your error, I don't think it is
a correct fix. It could cause other issues and is an example of one of
those 'fixes' which will likely cause more subtle and difficult to
identify issues. 

The 'org-open-lin-functions is supposed to be either nil or a list of
functions which take a single argument. What you have done is add t to
that list. This likely works as t evaluates to itself, but I think it
will completely break org's handling of [[link text]] style links
because when org runs this hook, it will always return t, telling org
that your custom functions have handled it. You may have tested your fix
and found that it looked like it worked, but note the details in the doc
string for that hook. i.e.

"They will be called for links that look like [[link text][description]]
when LINK TEXT does not have a protocol like "http:" and does not look
like a filename (e.g. "./blue.png")"

Your original error is due to something in your config adding a function
to that hook which does not exist. What you need to do is either define
that function (or find it's definition) or remove it from your config
i.e. remove the add-hook line which adds the function.

Note that the default setting is nil i.e. most installations probably
don't have anything in this hook unless they have some special url
format or they have added a package which provides custom url
handling. If you found the line and just changed the function name to t
as a fix, you can safely just remove the line completely.
