[Opensim-users] Error from "save oar"

[John Hopkin]

I'm getting errors (see below) whenever I try "save oar". This occurs
from any of the 11 regions, whether or not only one is up at a time,
and regardless of how many assets are in that region (minimum is 1).

The errors are produced immediately when "save oar <filename>" is
entered.

Any ideas?

Spec: Ubuntu Karmic, Mono 2.6, OSGrid UGAIM, 

Output:
