toWebCoreString() in V8Binding.cpp in WebCore will null pointer deref if passed an empty handle. Sometimes when invoking ScriptCallStack::callLocation(), we would get an empty handle for the script name. See: http://code.google.com/p/chromium/issues/detail?id=45004

Comment on attachment 57035 [details] Fixes http://code.google.com/p/chromium/issues/detail?id=45004 WebCore/bindings/v8/ScriptCallStack.cpp:75 + *functionName = toWebCoreString(functionNameValue.IsEmpty() ? v8::Undefined() : functionNameValue); You know what toWebCoreString from undefined will look like? (I am not sure). Is that what you need?
