           Summary: [v8] empty handler is used to access native DOM window
                    implementaton
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org

There are crashes in v8::Object::GetPointerFromInternalField(int) due to empty
handle (this is null in ::GetPointerFromInternalField).  This handle
comes from V8DOMWrapper::lookupDOMWrapper (see
http://trac.webkit.org/browser/trunk/WebCore/bindings/v8/V8Proxy.cpp?rev=49510)
which means that somehow we failed to lookup (traversing proto chain)
DOM window from the current global (which sounds weird to me, but I
know too little about isolated worlds).  Maybe it somehow related to
out of memory condition.

The sample stack trace:
