bug#17966: 24.4.50; Error while saving bookmarks: Unknown button type `help-xref'

[Dani Moncayo]

emacs -Q
(set-language-environment 'latin-1)
(info "(emacs)Regexp Backslash")
C-u 9 C-n
C-x r m foo RET
M-x bookmark-save RET

At that moment, a *Bookmarks* buffers appears and the echo area shows
the message "Unknown button type `help-xref'".

I can't even exit Emacs, because that implies saving the bookmarks,
which againg triggers the above error.  (I have to move point to another
place, define the bookmark there, and then save it).
