I don't find information about this error

[Jordi Marcé Nogué]

Hello,

I'm using Petsc 2.3.1 in Debian (updated by apt-get) and I don't find
information in the web and in the troubleshooting section about this
error message:

> [0]PETSC ERROR: MatMatMult() line 6543 in src/mat/interface/matrix.c
> [0]PETSC ERROR: Nonconforming object sizes!
> [0]PETSC ERROR: fill=-2 must be > 0.0!

Maybe you know what does it mean because I've tried a lot of thing in my
code to solve this problem :-((( My Matrices have the same dimension.

regards,\j
