Here's another bug for you: moving a page into the user blog namespace makes it have commenting disabled, which is probably not often the desired behavior (such a move is usually done when people create personal pages in the mainspace).

I'm also struggling to make a perfectly legitimate gadget work, but that's a separate issue and I dunno what it's caused by.
