 Replying to [ticket:1961 hamish]:
 > Hi,
 >
 > testing wxNVIZ in latest 6.5svn, I get an error and 100% CPU use if I
 select '3D view' in the map display window with just a vector map
 selected. (also tried with a 3D vector map, same thing) happens both on my
 linux and Wingrass-VM. It's recoverable once you switch back to '2D view'
 mode.

 new constant surface at z=0 with 50% transparency. (or at least that's the
 trick with tcl/tk nviz + no raster to drape things on)

 It seems that this is already done. Try r56122 which should fix the
 traceback.
