[Darin Adler]

Caused by http://trac.webkit.org/changeset/42623 and that was the fix for bug 25223.

[Darin Adler]

No idea how to reproduce this in a test case, but it's 100% reproducible in Safari.

*** Bug 25388 has been marked as a duplicate of this bug. ***

[Darin Fisher (:fishd, Google)]

I'm not sure this was the correct change.  I think you might still want to allow scrolling when m_currentHistoryItem is null.  At least that would be required to retain the behavior of the code prior to r42623.

Here's the patch I think should have been applied:

-    bool shouldScroll = !formData && !m_currentHistoryItem->formData() && urlsMatchItem(item);
+    bool shouldScroll = !formData && (!m_currentHistoryItem || !m_currentHistoryItem->formData()) && urlsMatchItem(item);

Interesting. That was my original patch, in fact!

But then I formed the impression that the shouldScroll code would fail if m_currentHistoryItem was 0 because of the call to saveScrollPositionAndViewStateToItem. I now see that was incorrect. I'll make the change you suggest.
