Empty notifications

I have two empty notifications, probably related to a couple of bogus Smart imports I tried just to make the GUI show me strings to translate. However, as they are totally empty, I can't mark them as read so they lie there and nag me. And every time I open the site I get a light green empty banner that shrinks to a small square after a second and goes away after five seconds, which I assume is also these empty notifications.

Fixed.

Thanks!
