Subject: 23.1.50; describe-font complains define-button-type: Unknown button type `help-xref'
Date: Tue, 08 Dec 2009 22:46:48 +0100

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

emacs -Q
M-x describe-font
define-button-type: Unknown button type `help-xref'
M-x report-emacs-bug
C-x k
M-x describe-font
  <<works fine>>

This is the error trace:
