I also had this problem ones, after searching why i couldn't restore my db I
looked in the original database and there the problem was.
When you add a field to a table thas is a not null field,but you don't set a
value for every record in the table then you get these error.

I don't now if there are any other possibilitys but I hoop it helps.

regards
