The following patch should fix it:

--- tex.el      24 Jun 2006 12:00:49 +0200      5.579
+++ tex.el      30 Jun 2006 23:42:08 +0200

            (lambda ()
              (when (executable-find "texdoc")
-               (TeX-search-files nil '("dvi" "pdf" "ps" "txt" "html") t t)))

            (lambda (doc)
              (call-process "texdoc" nil 0 nil doc)))
     (latex-info (latex-mode)

However, it might be better to add a variable for specifying available
TeX trees (which could have a calculated value as default, just like
`TeX-macro-global') and using that for searching below the doc
subdirectory.  Alternatively the variable could be used to give the
paths to doc directories directly.
