I seems there were good reasons not to immediately update because the
new versions had another bug (which has been fixed too). You can find
more details in the Cisco release notes (see the link below for
further references).

Since the original post, I have spent some time to analyse the
problem and there is even one setup which is running a modified
FreeBSD installation to work around the problem.
