Subject: Invalid face height
Date: Tue, 16 Jun 2009 10:46:02 +0200

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"

  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.

Hi,

function reftex-toc of the reftex package also does not work:

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).

Please add the backtrace (and a recipe to reproduce the problem, as
well) if possible.

1. emacs -q
2. Alt-x tabbar-mode
3. Invalid face height:0.0


Alternative 2:
2. Alt-x ecb-activate
3. ECB 2.3.2:Errors during the layout setup of ECB. (error-type: error, error-
data: (Window width 0 too small (after splitting)"))

Alternative 3:
2. start latex file, switch to latex-mode
3. Alt-x reftex-toc
4. Window height 0 too small (after splitting)

This is all to reproduce wihtout any of my .emacs customizations involved. I 
testet this with 
- the ubuntu packages from http://ppa.launchpad.net/ubuntu-elisp/ppa/ubuntu 
jaunty main
- the cvs version from :pserver:anonymous <at> cvs.savannah.gnu.org:/sources/emacs

All this works well in console mode: emacs -nw

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

Hi,

Hi,

I have the following in my .emacs:

(require 'tabbar)

(set-face-attribute
 'tabbar-default-face nil
 :background "gray60")
(set-face-attribute
 'tabbar-unselected-face nil
 :background "gray85"
 :foreground "gray30"
 :box nil)
(set-face-attribute
 'tabbar-selected-face nil
 :background "#f2f2f6"
 :foreground "black"
 :box nil)
(set-face-attribute
 'tabbar-button-face nil
 :box '(:line-width 1 :color "gray72" :style released-button))
(set-face-attribute
 'tabbar-separator-face nil
 :height 1)
(when (require 'tabbar nil t)
      (setq tabbar-buffer-groups-function
    	(lambda (b) (list "All Buffers")))
      (setq tabbar-buffer-list-function
    	(lambda ()
    	  (remove-if
    	   (lambda(buffer)
    	     (find (aref (buffer-name buffer) 0) " *"))
    	   (buffer-list))))
      (tabbar-mode))


With this it does not work for more than 2 months now.

If I remove that and set 

(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(tabbar-default ((nil (:height 1)))))

in my .emacs, I can manually start tabbar (alt-x tabbar-mode).

If I insert (require 'tabbar) in .emacs, however, it again gives me the 
previous face error.

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?

The command tabbar-mode isn't part of Emacs.  Again, please show the
backtrace (Options => Enter Debugger on Error).

Same for ecb-activate.

I had to add M-x reftex-mode before being able to do M-x reftex-toc.
But it worked just fine without giving me any error.

Hi Stefan,

please see the previous post. I've already worked around it by setting 
"LANG=C". The question is now, why it does not work with other LANG settings.

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.

Sorry, nobody could reproduce this. Looks like it might have been
dependent on quite a few local customizations and packages that are not
part of Emacs.
