error message 'langs[...] is null or not an object'

What steps will reproduce the problem?
1. install jN plugins package
2. open a file with customed suffix like '.jsxxx'
3. toggle tab to the file

What is the expected output?
error message 'Editor.langs[..] is null or not an object' shown on a dialog

What version of the product are you using? On what operating system?
npp 5.9.8
jN 1.0.34

I tried to debug this issue and find the problem.
jN plugin XML.js will cause this issue at line 4.

script snippet:
this.menu.disabled = langs[v.lang].toLowerCase()!="xml";

while file type not in langs list, the langs[v.lang] means undefined, so it is 
no method 'toLowerCase'.

I modified the line.

script snippet:
this.menu.disabled = !langs[v.lang] || (langs[v.lang] && 
langs[v.lang].toLowerCase() != "xml");

then it works.
