I ad such a problem once, there was a space at the end of the line
somewhere.
You may filter the data like this:

cat theinputfile.txt | sed 's+ ++g' > theinputfile_clean.txt

then import 
v.in.ascii input=theinputfile_clean.txt output=theoutput fs=',' -z z=3

In fact the message should indicate the offending line, but I
don't know how to implement that. Maybe the author of v.in.ascii knows.

Please let us know if this trick helped.
