Bug 14116 – DocumentLoader:frameLoader() crash in WebKit-using application (but not Safari) using 3.0b; fixed sometime between [22041] and [23487]

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: New Bugs

[Evan Schoenberg]

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].
