Error while redistribute the Epetra.MultiVector my_nodes

[xander9595]

Hi, I am facing issues while running PD.py.
Form the message below, it seems like some error happens when redistribute the Epetra.MultiVector my_nodes.
I also tring to run some easy redistribute example by Pytrilinos 12.18.1, like Vector , CrsMatrix. It all works. However, when I was tring to redistribute the MultiVector, I got the same error as running PD.py.
So, how can I fix this bug?@johntfoster

Here is the error message:

:mpiexec -np 2 python PD.py
