bug#24529: 11.89.5; Bug: org-table/auctex error "Marker does not point anywhere"

[Tamulis, Andrius]

I get an error "Marker does not point anywhere" when using orgtbl-mode 
while using AUCTeX to edit a .tex file. The error does not happen if I 
rename the min.tex file to min.nottex, as then AUCTeX does not recognize 
the file and does not load. So this is a joint 
org-table/auctex/font-lock error, and I am submitting this bug to 
address@hidden and to address@hidden

I open the .tex file, get to the table I want to edit, then do M-x 
orgtbl-mode. I then tab a couple of times. Then make an edit - any edit. 
Tab again, and the error comes up.

I finally traced the error to the line

   '(font-lock-global-modes nil)

in my .emacs file. Comment this out, and the error does not happen.

I really don't like font-lock, as I don't like all those colors. I'd 
prefer to have my font-lock-global-modes set to nil, somehow.

Minimal files and backtrace below.

Thanks,

Andrius
