[O] "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
