Ah, too bad - this is a problem of using a non-English locale!
The code above line 184 looks like this:

POINTSNUMBER="`v.info map=${VECTTMP} | grep 'Number of points' | awk
'{print $5}'`"

Since it searches for 'Number of points' but gets in German locale
'Anzahl Punkte'
not a single point is found. The correct line is

POINTSNUMBER="`v.info -t map=${VECTTMP} | grep points | cut -d'=' -f2`"

You may just edit the script locally to fix that.

Found the same in v.centroids, both fixed in 6.4.svn, 6.5, and 7.
Thanks for reporting it,
