This should have been very difficult to track down. 

ox-freemind.el does invoke `libxml-parse-xml-region'.  I think Emacs
should raise a runtime error (and not return nil) if the above API is
called but libxml is unavailable.

ps: This bug is a good excuse to audit "other" such wrapper calls (if
there are any) and make sure that they don't fall silently.
