Here is also a session in cowbuilder, that reproduces this problem:

ondra at fuji:~$ sudo cowbuilder --login

Please feel free to ask for more info. Are you able to reproduce it?
If it's a bug in update-alternatives, it may well be
that it happens in cowbuilder for me, but not for you. But I suggest
to reopen this bug until we find the real cause of the problem.
