Hm. The only thing I can say right now is that RootI::new() actually
shouldn't be called, because it is meant to be absent (and eventually it
will be or throw an exception). If this is the reason,
PrimarySeqI::translate seems to create an object from an interface or a
class that does not implement new() itself (which now every class is
supposed to do), or chains back to the inherited (unlikely).

As a general comment to the list, it is probably not a good idea to check
out the main trunk for those people who aren't involved in the
RootI-transition until we've settled this. It's a really a development-only
trunk at the moment. If you're eager to get the newest version for the
latest features, you better wait 1-2 weeks or maybe even a bit more.
