bug#3586: Invalid face height

[Chong Yidong]

Tabbar mode is not distributed with Emacs, so you will have to point us
to the exact version you are using.

I can't reproduce this, using the reftex-toc mode distributed with Emacs
CVS.

emacs -Q
M-: (require 'reftex-toc) RET
C-x C-f /path/to/file.tex RET
M-x reftex-toc RET

The reftex-toc window shows up, with no problems.

Hi,

I finally found the bug: My locale was not the default one:

$ echo $LANG
de_DE.UTF-8

After setting it LANG=C emacs works with tabbar, reftex, and ecb!

So the question is, why?

Maybe you retry to reproduce the bug by setting LANG to the German locale?

Regards,
wr

I am unable to reproduce the bug with de_DE.UTF-8.

LANG=de_DE.UTF-8 emacs -Q
M-: (require 'reftex-toc) RET
C-x C-f /path/to/file.tex RET
M-x reftex-toc RET

=> no error.

Hi,

with the latest Emacs CVS version
GNU Emacs 23.0.94.1 (i486-pc-linux-gnu, GTK+ Version 2.16.1)
 of 2009-06-15 on lychee, modified by Debian

there are several bugs related to the following error:

Debugger entered--Lisp error: (error "Invalid face height" 0.0)
  internal-set-lisp-face-attribute(tabbar-default :height 0.0 #<frame  0xa3fd8b8>)
  set-face-attribute(tabbar-default #<frame  0xa3fd8b8> :inherit variable-pitch :height 0.0 :foreground "gray50" 
:background "gray75")
  apply(set-face-attribute tabbar-default #<frame  0xa3fd8b8> (:inherit variable-pitch :height 0.0 :foreground "gray50" 
:background "gray75"))
  face-spec-set-2(tabbar-default #<frame  0xa3fd8b8> (((... ...) :inherit variable-pitch :height 0.0 :foreground "grey75" 
:background "gray50") ((... ...) :inherit variable-pitch :height 0.0 :foreground "black" :background "white") ((... ...) 
:inherit variable-pitch :height 0.0 :foreground "white" :background "black") (t :inherit variable-pitch :height 0.0 
:foreground "gray50" :background "gray75")))
  custom-declare-face(tabbar-default (((... ...) :inherit variable-pitch :height 0.0 :foreground "grey75" :background 
"gray50") ((... ...) :inherit variable-pitch :height 0.0 :foreground "black" :background "white") ((... ...) :inherit 
variable-pitch :height 0.0 :foreground "white" :background "black") (t :inherit variable-pitch :height 0.0 :foreground 
"gray50" :background "gray75")) "Default face used in the tab bar." :group tabbar)
  (defface tabbar-default (quote (... ... ... ...)) "Default face used in the tab bar." :group (quote tabbar))
  eval-buffer(#<buffer  *load*> nil "/usr/share/emacs/site-lisp/emacs-goodies-el/tabbar.el" nil t)  ; Reading at buffer 
position 22128
  load-with-code-conversion("/usr/share/emacs/site-lisp/emacs-goodies-el/tabbar.el" "/usr/share/emacs/site-lisp/emacs-
goodies-el/tabbar.el" nil t)
  require(tabbar)
  eval((require (quote tabbar)))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp nil nil)


Basically the following modes pose problems or are unsuable at all:

ecb: does not start
tabbar: does not start
org-mode: does not switch automatically to agenda buffer if width not big enough for horizontal split

Unfortunately, no bug in the archives resembles this one from my understanding.

Why is this face defined to have a height of 0.0?
This looks really odd (I'm not surprised Emacs signals it as an invalid
face height, although it might also be OK to change Emacs to accept such
values).

Your question actually helped to enable tabbar again. In face customization of 
tabbar I set "With Defaults" in "Value Menu". Now it works again.
