I ran across this problem today as well, on the new Grass5.0.0pre4.
I tried it with the files below on two machines with the same result.
  (i686 RedHat 7.3 and a i686 Debian 3.0; GRASS compiled from source on 
both)

Steps:
Imported .shp files into grass vector files with v.in.shape.
g.region -d
d.vect coastline_chch
d.zoom
upon zooming in, the display goes blank (most times). at this point:
   -zooming back out gets you back to a plot. (sometimes not until second 
button-2 click)
     (may be nothing, but it gives a message about limit of default region 
reached,
      also got it to complain about needing to reset the resolution once, 
needed to restart x0)
   -zooming in just gives further blank screens
   -quiting: if you quit with the screen blanked, and try running d.zoom 
again,
      it starts up in interactive mode asking for a mandatory raster file. 
Need to
      d.erase before you can d.vect again and have anything actually show 
up and zoom again.      If you zoom out and quit with a plot up, you can 
continue plot/zoom..

[also, the Tcl/Tk menu -> Quit, stop all X monitors doesn't work anymore. 
Need to d.mon stop=x0]



Should this stuff be submitted into the bug tracking system, or is here 
suitable enough??
