This is not really a bug. grid is not compatible with 
standard R graphics, and just starting a device by 
calling postscript() or x11() will not work. You need 
to call the grid functions grid.start() and 
grid.stop() when you enter and exit grid graphics.

If you're only interested in the lattice stuff, then 
the proper way to initiate a postscript (or x11) 
device is to call 

trellis.device(postscript, file="foo"). 

You should probably also read the documentation for 
trellis.device, as you might not like the current 
defaults.
