We're seeing a similar issue in capybara-webkit.  See the discussion here: http://git.io/jKcw_g.

Basically, if deleteLater causes a WebPage to be deleted while evaluateJavaScript is still running, the resultant message is delivered by WebCore/JSC internals to an invalid object.  This results in a segfault.

Although the errors in capybara-webkit require redesign to work properly, given that loadFinished does not signify that javaScriptWindowObjectCleared has been fired, it is still concerning that using deleteLater still causes a segfault, even though it is supposed to wait for all signals to be delivered.
