This is a bug detected in bug 84908. In a nutshell, an onresize event handler in the popup window can be non-deterministically reclaimed by GC. For more details, please look at the chromium issue 123642: http://code.google.com/p/chromium/issues/detail?id=123642
The patch for bug 84908 fixes V8LazyEventListner.cpp so that an event listener object is re-created if the event listener object is already reclaimed. This is just a temporary fix. We should fix the code so that an alive event listener object is never reclaimed. Please look at bug 84908 and chromium issue 123642 for more details.
V8 is gone.
