This is not reproducible.

Could you do a traceback() ? And please make sure you start with an empty 
workspace. I very much doubt it's a lattice problem, since bwplot is not 
supposed to call segments() at any point.

A wild guess would be that you are using some sort of S-PLUS code without 
telling us.
