--- Comment #4 from Vincent Povirk madewokherd@gmail.com 2011-10-03 09:16:51 CDT --- Actually, the crash looks very similar to a bug we're tracking internally at CodeWeavers, where I suspect a refcounting problem in mshtml causing us to use a COM interface after it's freed. Can you try with warn+heap? If I'm right, that should make the failure more consistent.
