           Summary: DocumentLoader:frameLoader() crash in WebKit-using
                    application (but not Safari) using 3.0b; fixed sometime
                    between [22041] and [23487]
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
               URL: http://www.wired.com
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Blocker
          Priority: P2
         Component: New Bugs

bdash asked me to submit this to help prevent a regression.

Loading many webpages in Vienna, an rss reader which utilizes WebKit, using the
WebKit.framework supplied with Safari 3.0b1 ([22041]), leads to an immediate
crash.  Loading the same pages in Safari 3.0b1 itself does not cause a crash,
nor does loading the same pages in Vienna using OS X 10.4.9's original WebKit.

This crash does *not* exist at [23487].
