Bug 21608 – REGRESSION: Assertion failure in MainResourceLoader::didFinishLoading() at ynet.co.il

• Status: RESOLVED
• Resolution: INVALID
• Component: Page Loading

Loading the URL causes an assertion failure:

ASSERTION FAILED: shouldLoadAsEmptyDocument(frameLoader()->activeDocumentLoader()->url()) || !defersLoading()
(WebCore/loader/MainResourceLoader.cpp:310 virtual void WebCore::MainResourceLoader::didFinishLoading())

Backtrace:

}

I am hitting this very frequently on many websites.

Note, that this radar and the underlying CFNetwork radar have been closed, but the ASSERT still reproduces if you remove the #if !USE(CF) guards. =(
