           Summary: localStorage setItem converting value argument to
                    string before saving
           Product: WebKit
           Version: 528+ (Nightly build)

        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

According to http://dev.w3.org/html5/webstorage/#the-storage-interface - Storage.setItem is defined this way:

setter creator void setItem(in DOMString key, in any data);

However, Safari 5 / Chrome 5 converts argument data to string before storing, thereby producing some unexpected errors. For example:

// let's store a boolean value
window.localStorage.setItem('a', true);

// typeof returns string
typeof window.localStorage.getItem('a');

// equality does not work
window.localStorage.getItem('a') == true; //evaluates to false

Is this the correct behaviour or will this be fixed? I think this is a bug?
