            Bug ID: 248184
           Summary: JSValue API converts String objects to NSDictionary
                    instead of NSString
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: timothy at apple.com

If a script returns a result or passes a function a String object (not a value) -- like "new String('Test')". And that ObjC -[JSValue toObject] method is called, it will return a NSDictionary with keys for each character instead of an NSString.

This was surprising to me, but it does make sense at a fundamental level. I would just expect an NSString since it is not that useful as an NSDictionary.
