try turning up the Debug message level.

G6> g.gisenv set="DEBUG=5"
G6> v.in.ascii input=coords.txt output=thevect

That might help you see what's going on.
(column includes a non-number so treated as a string? column header
line? blank line at end of file?)

when finished turn debug level down to 0. The higher the number (up to
5) the more detailed messages you'll see. 5 is _very_ verbose.
