I suppose more a glitch.  AFAIK there is currently no distinction
between real link target paths (files, directories etc.) and
expressions that would qualify as a query part of a link (e.g. like
the regexp).

Maybe fiddling with percent escaping (Cf. org-link-escape and
org-link-unescape) might provide a way to protect the slashes from
conversion.
