It somehow seems awfully lot like this bug I've reported. Its just
during a restore I notished the problem:
http://bugs.bacula.org/view.php?id=1194
I havent had time to dig more into it, but it seems like the storage
daemon actually cached the slot number from the catalog, making
update-slots not effective even it ran correctly and updated the slots.
