We've had a few reports of loosing data in Umbrello (not loads I'm
glad to say, 3 or 4).  It is of course very worrying and worse still
there's not much can be done about it since there's no way to recreate
the problem.

The best I can say is to take backups as nesessary which is far from
satisfactory.  Hopefully the problem can be tracked down before too
long.
