           Summary: Native error prototype objects should be Error
                    instances
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P3
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kent.hansen at nokia.com


ECMA-262, 5th edition, 15.11.7.7: "Each NativeError prototype object is an Error object (its [[Class]] is "Error")"

Object.prototype.toString.call(TypeError.prototype)

produces "[object Object]" with JSC, whereas SpiderMonkey and V8 both produce "[object Error"], as expected. Same for the other *Error prototypes.
