This somehow happens to be problematic to me too, if for some reason the inclusion of the file isn't made by Org mode itself.
For example, we know that "#+INCLUDE:" keywords at the start of the line are Org mode specific includes, and you can place the file references in the first argument with the literal characters (that is: no need to do percent encoding/escaping). However, hyperlinks (that is: those between "[[" and "]]") demand percent encoding/escaping. But, it seems that the Org-to-LaTeX exporter isn't translating the hyperlinks to something LaTeX understands (LaTeX expects literal characters, and "%" is the start of a comment). Also, as a final note, the default grffile inclusion in the Org-to-LaTeX (and to PDF also) doesn't include the necessary options to make LaTeX accept spaces and accents in file names. That's OK for compatibility reasons, and if you do want to force it to accept such special characters, use the grffilesetup LaTeX command with the proper grffile options. Personally, I like to go the safest route: remove special characters from file names whenever I don't need them. I generally replace spaces with underscores, and leave letters without accent. This also avoids having to deal with the broken percent decoding/unescaping when doing Org-to-LaTeX exports.
