I see your fix, which as you comment is a bit hairy. ;) 

Actually I think, that maybe throwing an exception would be a cleaner
way here and in other places, where something tries to access
non-existing Elements (like the other "Element &get()" methods.
However then all uses of get() will need to catch possible exceptions.
I implemented an example of this in attached files. There, the right
outlet gets a bang in the catch block, if an exception occurs, but
that's just for illustration and should  be removed, as the list is
not empty in fact, when the exception is thrown.

Ciao
