..I had a simular problem a while back, which got fixed, but it was too long ago to remember the solution and I couldn't locate the thread on the the mailing list archive..

are you running the latest grass 5.0.0 version or one of the old preX versions???
or something even older?

these steps always work for me on a good vector file:
v.support vectorfile
g.region vect=vectorfile
d.vect vectorfile
d.zoom


does the vector file display but then disapear when you zoom in?
and zooming works correctly on a raster file?
