That looks like a possible database corruption. I'd start by
using the -v switch in gbak to establish which table contains
the error, then verify with isql (or an equivalent query tool)
that there is a problem with that table. If those tests show
a problem, then I'd copy the database and run gfix on the copy
to see if it corrects the problem.

I'd also check the server logs for indications of problems
and get back to the list with whatever information you find.
