[Rd] segfault when applying strange coercion (PR#2923)

[ligges at statistik.uni-dortmund.de]

I made a mistake -- and R crashed. A (more or less) reproducible example 
seems to be:

   x <- matrix(nrow=20000, ncol=20)
   x$any <- numeric(0)

It is possible to crash R by executing these lines several times (1 - 
20) on Windows as well as on Solaris (might be related to PR#2880 - 
let's call it "non-existing list elements")
