if all the other checks fail, and there is a meta tag with no http-equiv attribute, the code calls .lower() on null. see also http://code.google.com/p/chromium/issues/detail?id=34961 for repro steps using chrome.

Comment on attachment 50062 [details] fix style warning Can we please just remove WebDocument::applicationID. As I mentioned to Aaron, it doesn't belong here and can be implemented purely in terms of WebKit APIs.

Darin, I knew you'd say that. I am going to start pulling it out soon. Can johnnyg just fix this immediate issue in the meantime?

Because notifications are hooked up to applicationID() already, this is causing real crashes when people use notifications... so i'd rather not wait for a large refactor to fix that.

Sorry to give you a hard time about the applicationID thing. I would have r+'d the patch before if it didn't have the style issue.
