Did you do anything (update GRASS, spgrass6, GDAL/OGR, R) yesterday?

What does sessionInfo() in R say?

getSites6sp() is just a wrapper for the regular readVECT6() interface, by 
the way. If you want to try to debug this, say debug(readVECT6), run the 
command, and look at the contents of shname and the cmd string starting 
with "v.out.ogr". That seems to be trying to write to a file with an empty 
name - is this a character set issue (what locale are you using, were 
there any non-ASCII characters in the name)?
