problem exporting to latex with latest git release

[Eric S Fraga <ucecesf@ucl.ac.uk>]

Carsten et al.,

I have run into the following problem with the latest git release of
org-mode.  When attempting to export an org file as latex, I get the
following (truncated to remove excess amount of file contents etc)
debug trace:

If I've removed too much, I'm happy to send a full trace.  The only
particularly out of the ordinary contents in this latex file is a
#+begin_src matlab 
block.

The git log gives the following two as the latest commits and the
second looks suspiciously as a possible culprit?

Maybe I missed a configuration option that is necessary?

Thanks,
