I have a vague memory of encountering something along these lines a long 
time ago. The problem is that for some reason the configuration information 
passed to kupu is returning a javascript object for lib_prefix instead of a 
string.

I think when this happened before it was because of some javascript library 
doing things to the browser's XML node prototype which were incompatible 
with kupu. Anyway the problem is in kupuhelpers.js, LoadDictFromXML (or 
_load_dict_helper) which should return an object with a string attribute 
lib_prefix, but in fact it is returning an object for lib_prefix. Someone 
with access to your system would need to step through the code with a 
debugger and figure out why this is failing.
