From etc/NEWS:

  * Incompatible Lisp Changes in Emacs 24.1

  ** A backquote not followed by a space is now always treated as new-style.

and psgml-parse.el contains:

parse-sgml.el is not bundled with Emacs, so please attach it,

Hi Stefan,

think I misunderstood your request.
You want the file in use here?

Attached.
BTW misspelled it's name, sorry for that.

Indeed.

> You want the file in use here?

Yes, thanks.  Tho others have already pointed out the source of the
problem: this file uses old-style backquotes and has several places
where these backquotes are not followed by a space.
It should be changed to use new-style backquotes instead.
