Comment (by pmav99):

 I also created a vector map that contained a single line element. I
 exported and tried to reimport it using `v.import`. This is the exported
 `GeoJSON` file:
 {{{
 {
 "type": "FeatureCollection",
 "crs": { "type": "name", "properties": { "name":
 "urn:ogc:def:crs:OGC:1.3:CRS84" } },

 "features": [
 { "type": "Feature", "properties": { "cat": 3 }, "geometry": { "type":
 "LineString", "coordinates": [ [ -78.691347885901351, 35.767500940375896
 ], [ -78.689522060322943, 35.768756195461052 ] ] } }
 ]
 }
 }}}
 And this is the output of `v.import` (i.e. everything works just fine):
 {{{
