latex-mode frequently re-fontifies buffer

[Thorsten Jolitz]

Hi List, 

I tried to use outshine/navi-mode with latex-mode, and it works quite
well so far, I even added a few convenience functions to outshine (still
in the tj-outshine branch), see the PS. 

But there is a slightly annoying issue: latex-mode seems to re-fontify
the buffer frequently, so when I modify and save the buffer, quite often
the (Org-style) headline fontification is lost and all outshine headers
are shown in comment font. 

I have to call 'M-x latex-mode' again to get the outshine headline fonts
back. This did not happen in any other major-mode where I used
outline-minor-mode with outshine so far.

I'm not sure where to look for the culprit of this behaviour - any hints
would be welcome.

These functions depends on customizable variable:
