Okay, something is haywire in Bugzilla's spam filter and it's not letting me post the clone message.

I have a github project in which simply opening one file reproduces this bug 100% of the time.  Link is here:  https://timboudreau.com/files/nb_bug_271676.txt

100% reproducible if you clone https://github.com/timboudreau/cfig and open cfig.js

I will attach a simple patch that fixes the problem.

Patch to avoid recursively trying to resolve the same element

Simply tests to see if the method is going to call itself with the same arguments as it is currently called with.
