Could it be related to Ticket #1139?
Anyways I've found that v.report has a strange behavior, i.e. the perimeter
value calculated sometimes is not correct or is zero (grass 6.5svn on
debian). I didn't report it yet because I wasn't able to replicate the
error again. I see that giohappy has the same problem.
Ideas?

Best,
madi
