Just fixing a null deref in DOMURL when the script execution context doesn't exist at the time of creation. I'll post a patch in a minute.

Please capitalize the 1st character.

> +        * fast/dom/domurl-script-execution-context-crash.html: Added.

Since DOMURL is only used for blob URL, I think we'd better put this new test under fast/files.

> LayoutTests/fast/dom/domurl-script-execution-context-crash.html:6
> +        e.apply(w,['webkitURL']);

Please add a space after comma.

> LayoutTests/fast/dom/domurl-script-execution-context-crash.html:16
> +    setTimeout(crash,30);

ditto.

> LayoutTests/fast/dom/domurl-script-execution-context-crash.html:26
> +e=(w=open()).eval;

Please add space before and after 2 "=" operators.
