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.

Emacs did return a runtime error, it was simply my mistake not to have
noticed it in the Message buffer.

This is what Emacs does.
From xml.c: 96
message1 ("libxml2 library not found");
and message1 (based on other uses elsewhere) seems to be used for
ordinary echo area messages (like prompt strings etc) as opposed to an
"error" message.
----------------------------------------------------------------
It is easy to check though.
I don't have access to a Windows machine. It should really be an error
and not a simple informative message. Try this:
1. Remove libxml
2. M-x toggle-debug-on-error RET
3. Export to freemind
Do you now get a backtrace buffer?
