After visiting some newspaper web pages (full of all sorts of Flash-based advertsing) WebKit.app crashed a few seconds later.

I have seen this stack trace before, so I guess I will mark the bug as confirmed. Which version of the Flash player are you using? Do you have any clue which sites you were viewing?

Good point about the Flash version - it is a beta of Flash 10: 10.0.0.525 (from the bundle Info.plist)

Here are the sites I believe that I have visited during the session:

http://politiken.dk (several pages)
http://berlingske.dk (several pages)
http://guardian.co.uk - specifically:

http://www.guardian.co.uk/technology/audio/2008/jul/07/facebook.digitaladvertising

I am certain, though, that I have seen crashes with Flash_EnforceLocalSecurity in the stack trace also with earlier (non-beta) versions of Flash. It used to happen all the time, but I don't know if it went away thanks to a bug fix or because I deleted some Flash preference file I found.

I was wondering if this was caused by a Flash issue, as the other person mentioned he had just upgraded to Flash 10, but it seems that the new beta of Flash came out around the same time that we made a change in WebKit. ;-)

If get a crash with a stack trace that has any WebKit symbols above a Flash_EnforceLocalSecurity, please post it as a WebKit bug.

This bug seems to be a duplicate of bug 19926, which thankfully has a reproducible test case.
