Re: iterable argument required - bug?

What you did was trying to find the uri of something that was not a string.

attached are files to show the behaviour on (1) non-strings, and (2) strings that do not encode uri's. 

Timbl, what should the behavior be? Currently if the file has either error cwm throws an exception. Should it do that? Should it keep going?
