I think this is related to the fact that the first row of the matrix does not have any nonzero entries. Is that it?

Laryssa:
It's hard to tell. The approach to debugging these sorts of questions is to create a small program that sets up the matrix the same way you do, performs the vmult, and does nothing else -- in other words, we need a minimal reproducing example. We'd be happy to take a look at what's going on if we had such a small test case.
