Holy crap, that's it. I had LANG set to "en_us.UTF-8" on one system  
and "en_US.UTF-8" on the other... and, apparently, that's enough to  
trigger an error at urxvt startup:

   urxvt: the locale is not supported by Xlib, working without locale  
support.

and make copy/paste later fail in mysterious ways.

So there's that mystery solved! Thank you. (Although now the question  
is *why* a bad value for that environment variable breaks copy/paste  
so spectacularly.)
