Test
Using a debug build of WebKit, open the attached the test case in Safari and follow the instructions. Then the assert ASSERT(!m_mainFrame->coreFrame()->loader().frameHasLoaded() || !m_pendingNavigationID) will fail in WebPage::reload() because m_pendingNavigationID is nonzero.
For completeness, I used a debug build of Mac WebKit at r214187.</pre>
