Thank you for your answer Roger,
Because there are two routes used depending on the setting of the plugin=
argument, could you look at ogrDrivers() and see if you have an OGR GRASS
vector driver, and if so, try to set plugin= manually to TRUE and FALSE?
The output of ogrDrivers() shows that I do not have the GRASS driver
(tagged as FALSE).
Note that GRASS 7.0svn is the development version, snd is very much a moving
target - do you have to use this version?
No, I do not have to use it, it is plein curiosity/testing of new
features. However I reproduced the problem on the 6.4 version.
I suspect that for some reason v.out.ogr is failing, so the file is not
written. Next, ogrInfo() fails to find it.
The latest (0.6-23) spgrass6 has a fix for a specific problem in the layer
parameter of v.out.ogr in GRASS7 - I see that you are using the previous
spgrass6. Could you try updating spgrass6?
If that doesn't work, please move thread only to grass-stats, and try
using v.out.ogr to export the vector to the GRASS mapset temporary
directory manually - use g.tempfile to find out what the path to that
directory is. If v.out.ogr appears to complete without problems, do check
the temporary directory to be sure.

And GDAL 1.7.1 is not the current
version, which is 1.7.3. Did you install GDAL and/or GRASS from source, or
from binaries (in my experience, installing from source ensures more
consistency, and the GDAL/OGR GRASS plugins are often the source of problems
because of version mismatch).
I installed both GRASS 6.4 and GDAL/OGR from binaries, yes.
PS. The best list is probably:
http://grass.osgeo.org/statsgrass/index.php
OK. I am sending that message to that list, and keep R-sig-geo for
consistency. Sorry for cross-posting.
Thanks again,
Pierre

as it is more specific, and also seen by GRASS developers.
I tried to play with the different options but I did not succeed>
