Hej!

I posted to opensuse-factory before, but Greg KH suggested to take this problem to this mailing list (or upstream, but I think this is enough for now, until we know more).

Anyways, here's the problem:

Since Gnome 3.8 hit Tumbleweed last week, Emacs shows a curious problem when using AucTeX to typeset LaTeX documents.

When typesetting a LaTeX document, Emacs opens a new buffer with the LaTeX output in it. When the LaTeX run is finished, Emacs displays "LaTeX: successfully formatted {1} page" (with the appropriate number of pages). This also ends the LaTeX-process, allowing to use a new process, like LaTeX, Bibtex/Biblatex/Biber etc.

This is not a LaTeX problem, since it works correctly from console (and finishes the run). It is also not TeX-engine specific, since both XeLaTeX and pdfLaTeX show the same behaviour. Moreover, this does not seem to be an Emacs problem, since emacs-x11 (as opposed to emacs-gtk) does not show the same problem.

*However*, with the Gnome 3.8 update, Emacs does not do the last step, i.e. displaying that LaTeX finished successfully, and consequently, the LaTeX process never finishes. When calling a new LaTeX process, Emacs then first asks whether to kill the old (unfinished process), which needs to be accepted before a new LaTeX process can be called.

Emacs produces no error messages whatsoever, and I see no output when starting it from console, either.

The problem goes away when downgrading the Gnome-related packages in Tumbleweed to the normal 12.3 versions, which suggests that this is, in fact, a Gnome problem.

It seems as if something in Gnome 3.8's core breaks the process notifications and handlings between processes, but I have no idea what would.

The Emacs version does not matter, the behaviour is displayed with the standard 12.3 version, Tumbleweed version, my current compiled version and a fresh compile from Emacs master.

Any ideas? And what should I file a bug against?

Cheers, Peter
