I think you're being unfair:  this is a LaTeX bug, not an Sweave bug.

R is open source, so this is no mystery:  if you use [noae] then Sweave 
won't use the ae package in LaTeX.  The problem you were having with 
quotes is that the ae package doesn't define those.  If you choose not 
to use it, then you won't get the symbols that it does define.
