"org-nil" error in LaTeX export

"org-nil" error in LaTeX export

[Brenton Kenkel]

I am having a problem with exporting to LaTeX from org-mode. I am 
running org-mode 7.5 in Emacs 23.1.1 on 64-bit Ubuntu 10.10. (I am using 
the stable version, but the same error occurs when I use the development 
version from git.) When I run "C-c C-e d", I receive the error message 
"Cannot open load file: org-nil". The file I am using and the backtrace 
output are pasted below.

Best wishes,
Brenton Kenkel

I cannot reproduce it -- can you test with a bare emacs -q ?

Also, please make sure to remove any previous Org installation.

Best,

I cannot reproduce it either: the only way that this could happen is
if the :for-backend property is missing when org-export-preprocess-string
is called. But org-export-latex-first-lines sets that explicitly - *if*
you have a consistent version of org.

But Brenton seems indeed to be using remnants of an old installation.
His backtrace shows:

The ":for-LaTeX t" stuff on the marked line seems to indicate left-overs that
have gone stale.
