Created attachment 232425 [details] crash log
You mentioned in the bug title that you suspect that the crash was caused "by CSS3 or [a] media plugin". Can you elaborate further, especially with respect to your suspicion that CSS3 may be the cause? Are you able to share the URL or markup that caused the crash? If so, please update the URL field of this bug and/or attach a test case with the markup. What were doing at the time of the crash?
you know, the same page , doesn't crash every time. when you clear the cache data and then access the url, it will crash. And I copy the whole page html ,run it as static page , it doesn't crash. it sounds like the mix effect. Any way, I will try my best, find the real killer, attach a test case .

wow, cool, thanks, man (In reply to comment #4) > 1 com.apple.WebCore 0x03e5dafc WebCore::SubframeLoader::loadMediaPlayerProxyPlugin(WebCore::Node*, WebCore::KURL const&, WTF::Vector<WTF::String, 0ul, WTF::CrashOnOverflow> const&, WTF::Vector<WTF::String, 0ul, WTF::CrashOnOverflow> const&) + 844 > > SubframeLoader::loadMediaPlayerProxyPlugin has been removed from WebKit and the iOS <video> implementation has been substantially rewritten so this specific crash can not happen with TOT WebKit.
