Simple fix

Note that even after applying this patch, the return value of GM_openInTab is a bit weird. Trying to access any property (except .window, as far as I can tell) throws a security violation (tested in Mozilla/5.0 (X11; Linux x86_64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2) - not sure why that is.

It always has been. Same origin weirdness with the sandbox, to the best of my knowledge.
