I hit this assertion: ASSERTION FAILED: ![_private previousItem] (WebKit/WebView.subproj/WebFrame.m:1447 -[WebFrame (WebPrivate) _recursiveGoToItem:fromItem:withLoadType:]) when doing the following: 1) Going to mail.google.com; I am already logged in so I reach my inbox 2) Clicking a message in the inbox to view it 3) Choosing History > Back
Previously in Radar as <rdar://problem/4401348> TOT REGRESSION: Assertion failure (![_private previousItem]) in -[WebFrame(WebPrivate) _recursiveGoToItem:fromItem:withLoadType:] @ mail.google.com The change in behavior here is that the redirects show up in the back/forward list at all. Previously, they didn't.
Works for me with r13244.

I also see the assertion off-and-on when clicking the "Back" button on my MS wireless mouse after viewing a mail message in Outlook Web Access from MS Exchange Server 2003. Steps to reproduce: 1. Log into Outlook Web Access. 2. Click on a mail message to view it. 3. Click "back" button on mouse. (May also happen with browser "Back" button.) 4. Repeat Steps 2 & 3 until the assertion occurs. (It does NOT occur every time.) Here is the assertion error message printed from a development (debug) build of WebKit r13607: ================= ASSERTION FAILED: ![_private previousItem] (/Users/ddkilzer/Projects/Cocoa/WebKit/WebKit/WebView/WebFrame.m:1460 -[WebFrame(WebPrivate) _recursiveGoToItem:fromItem:withLoadType:]) ================= Segmentation fault Here is the problem report
