[Orgmode] latex export problem

[Jörg Hagmann]

 Dear list,

I have an org file named "test.org" structured as follows (minimal example):

------minimal example------------
* Head
  text

* Second head
  :PROPERTIES:
  :EXPORT_OPTIONS: H:5 num:nil toc:t \n:nil @:t ::t |:t ^:{} -:t f:t 
*:t skip:nil d:nil tags:nil
  :EXPORT_TITLE: My Title
  :EXPORT_FILE_NAME: scripts/filename
  :END:


#+begin_src latex
\input gentium-ge
#+end_src

** section
   text
------end of minimal example-----------

I export the second head to a filename.tex file in a subdirectory (and 
convert it later to ConTeXt code, but that shouldn't matter here). I 
swear that this worked -- I have everything pertaining to my lectures in 
this file.
However, it stopped working recently (without updating org-mode). All I 
get when I export "Second Head" to latex is:
"No such file: /Users/me/test.org"
The cause is the #+begin_src ... #+end_src block

Did I inadvertently change some parameter? Or is it a bug (less likely)?

Thanks for your suggestions, Jörg
