When I configure any of my maven2 jobs, under "E-mail Notification" I have a
flag (boolean) called "Send e-mail for every unstable build".
It looks like this flag it not part of the peristent state; when I toggle the
flag, and then presses "Save", the next time I look at the configuration, the
flag does not have the same state as when I saved (but a random state, sometimes
true and sometimes false).

All the other flags works fine.
This problem does no occur in any of my ant-jobs.
