Very glad you like it (see more comments below)

Like Jeff said, this is a problem with relative links included in text 
that is meant to move around. I think we should not have relative links 
in descriptions (it's way better to break sandbox than to break user 
apps that want to reuse these descriptions).

Also, the nasty stacktrace that you accidentally discovered has already 
been fixed in the next release (that will go live at the end of the week).
