plugins/access-after-page-destroyed.html is crashing on the bots. The crash logs implicate DumpRenderTree!notificationListenerProc (see <http://build.webkit.org/results/Windows%20Release%20(Tests)/r65540%20(2834)/CrashLog_0e08_2010-08-17_15-52-59-764.txt>).

Looks like the crash is preceded by an assertion in debug builds: <http://build.webkit.org/results/Windows%20Debug%20(Tests)/r65606%20(18248)/CrashLog_0538_2010-08-18_07-01-47-171.txt> The failing assertion is: HRESULT hr = AccessibleObjectFromEvent(hwnd, idObject, idChild, &parentObject, &vChild); ASSERT(SUCCEEDED(hr)); Presumably we crash later because vChild is still null.
Created attachment 69491 [details] Don't assume AccessibleObjectFromEvent succeeds
Committed r68907: <http://trac.webkit.org/changeset/68907>
Do you know which event we're receiving that AccessibleObjectFromEvent fails on?
I think the bug here may be that AccessibilityController::resetToConsistentState() is not unhooking the "all events" hook set in AccessibilityController::addNotificationListener().
