Node webkit iframe set local storage item

Hi all, I have build an ember project and running it in node-webkit. In my ember app i am opening an iframe and trying to set LocalStorage on that iframe which raises a DomException :

Uncaught DOMException: Failed to execute ‘setItem’ on ‘Storage’: access is denied for this document.

Its an intermidiate issue sometimes it does’nt give error and everything works fine.
