Created a new location, Import, based on shapefile's .prj. When I run
'v.in.ogr input=/home/rshepard/data/grassdata/ODF/odf_own.shp
layer=odf_own'
an error in x_0 mis-match is found with the .shp file:

I'm curious how this can happen since the .prj and .shp come from the
same
source. If it is a user error I was not aware of it. A tarball with the
shapefiles is attached.
