Comment (by mlennert):

 Interestingly:


 {{{
 g.proj georef=point_eu_laea.shp location=test2
 Essai d'ouverture à l'aide d'OGR...
 ...réussi.
 Location <test2> created
 You can switch to the new location by
 `g.mapset mapset=PERMANENT location=test2`
 }}}

 but


 {{{
 v.in.ogr point_eu_laea.shp location=test
 ATTENTION: All available OGR layers will be imported into vector map
            <point_eu_laea>
 Location <test> created
 ERREUR :Invalid e-w resolution field: 0
 }}}

 Both are created, but:

 and in both I get:


 {{{
 g.proj -p

 because DEFAULT_WIND/WIND contains:

 {{{

 }}}

 which seems logical as a point does not have dimensions, but the default
 region should still be defined with one cell and a resolution of 1....

 So, yes, there seems to be a link to #2878...
