           Summary: Assertion failure in ~JSGlobalObject when loading
                    apple.com HTML5 transitions demo page
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://www.apple.com/html5/showcase/transitions/

I went to these URLs, in this order (I think):

http://webkit.org/blog-files/3d-transforms/poster-circle.html
http://webkit.org/blog-files/3d-transforms/morphing-cubes.html
http://annevankesteren.nl/
http://www.apple.com/html5/showcase/transitions/

When the last one was loading, I hit this assertion in ~JSGlobalObject():

    ASSERT(JSLock::currentThreadIsHoldingLock());

Here's the backtrace:
