[Paul Hiemstra]

Hi,

You don't give us a lot to work with. We have no idea what is present in 
the database object, what is present in the model5.out. Please give a 
piece of code that reproduces you error on our machine, preferably with 
a built in dataset such as the meuse dataset. Please also upgrade R and 
all relevant packages to the latest version. The example below works for 
me...

library(gstat)
data(meuse)
coordinates(meuse) = ~x+y
m <- vgm(.59, "Sph", 874, .04)
dum = krige.cv(log(zinc)~1, meuse, model = m)

cheers,
Paul
