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?
