Date: Sat, 10 Jan 2009 22:20:13 +0100 [thread overview]
Message-ID: <87y6xieu42.fsf@escher.local.home> (raw)
The bug described below still exists in GNU Emacs 23.0.60.28
(i686-pc-linux-gnu, GTK+ Version 2.14.4) of 2009-01-09 on escher, so I'm
submitting it to the bug tracker. Note that the cited sexp from
faces.el is now at line 1360, not 1307.

In GNU Emacs 23.0.60.4 (i686-pc-linux-gnu, GTK+ Version 2.12.0) of
2008-05-25 on escher
1. emacs -q
2. Put the cursor on any of the characters in the phrase "ABSOLUTELY NO
WARRANTY" in the splash screen.
3. Type C-u C-x =
4. In the resulting *Help* buffer click on the link labelled
"(variable-pitch (:slant oblique))"
=> Emacs beeps and throws the error in the Subject line.
This happens at line 1307 in faces.el, which is this sexp:
(insert "Face: " (symbol-name f))
when `f' gets the value `(:slant oblique)', which it does because the
list '(variable-pitch (:slant oblique)) is the value of 'face in the
plist of the character at point (as shown by text-properties-at). I
don't know what the best fix is.
(In earlier versions of Emacs, including CVS trunk of 2007-08-24, this
value was '(variable-pitch :slant oblique), and doing the above steps
does not raise an error, but the resulting *Help* buffer contains these
dubious lines:
Face: :slant undefined face.
Face: oblique undefined face.
But in this version a wrong type argument error is also raised by the
above recipe for plist 'face values such as '(variable-pitch :foreground
"red"), on the string. I could not determine when the change in the
representation of the plist value of 'face occurred, because I couldn't
figure out which part of the code constructs this plist.)
