BUG: LaTeX-Mode broken in Emacs in openSuse 12.2!

#1 
File mode specification error: (error "Face height does not produce a positive integer" 0.0)

Hi,

I asked this question yesterday at the Emacs-Mailinglist, but I think it is a bug of openSuse 12.2.

Between version 12.1 and version 12.2 of openSuse is a difference: Emacs is
partially broken. I tried with Emacs 23.3 from openSuse and a self compiled
Emacs 24.2. I tried with ICEWM and (how do you call it?) LX-something, I created a new user, always the same result!

After Emacs -Q --debug-init I get the message:

File mode specification error: (error "Face height does not produce a positive 
integer" tex-suscript-height)

as soon as I try to open a *.tex-file. And with my usual .emacs I get:

:~>Emacs --debug-init

   Debugger entered--Lisp error: (error "Face height does not produce a
     positive integer" 0.0)

This makes me :mad: !

Exept for installing 12.2 again, I ran out of ideas!

#2

I found a temporary solution to get Emacs and AucTeX working by adding those two lines to my .emacs at the custom-faces:

'(font-latex-subscript-face ((t nil)))
'(font-latex-superscript-face ((t nil)))

I opened a bug report 779248

This is a nightmare: A new version of openSuse brings a partially broken Emacs.

Hello,

I installed XEmacs (and not Auctex, as it should be included in XEmacs, and the Auctex-package
says it is incompatible with XEmacs).
Now (with 12.2) Auctex is not available at all, that is, opening a .tex-file with XEmacs creates something like
the naked Latex-style, without the possibilities for compilation etc. offered by Auctex.

On the Internet I found to add


(require 'tex-site)

to ~/.xemacs/.init.el, and that does something, namely now we get the additional menus


LaTeX
Command

however, on start-up we get an error-message


(1) (custom/warning) custom: widget custom-variable, option LaTeX-section-hook has no associated group

And furthermore, with my last Suse-version, 11.4, there were these nice menu-buttons (icons) for compilation
and for xdvi, which now disappeared.

And when for example calling Command/View, then I get the error message


(3) (menubar/warning) Error in `activate-menubar-hook': (invalid-change (Modification of this buffer not currently permitted  *Echo Area*))
Backtrace follows:
nil

So either the fix for getting back Auctex is somewhat broken, or Auctex itself is broken (or XEmacs).

Shall I open another thread, for XEmacs (not Emacs, which I do not use, and accordingly I do not know about it)?

Emacs is unable to calculate correctly, as long as the environment variable LC_NUMERIC is not set to C.

You can fix this by setting the variable via Yast–>“Editor for /etc/sysconfig”–>System–>Environment–>Language–>RC_LC_NUMERIC

AFAIK, emacs is a shell script. You could fix the environment locally in
that script to avoid having to change the global numeric environment,
which would affect numerical display in all applications.
