The debug package is an R package, an ESS package, or an emacs package?
I didn't see any reference to it in the ESS info file.

So do I.

Martin M observed in a different message that the use of
options(error=recover) hangs some things, but not others.

This is very odd, since what I experienced was that both the R session
and emacs were totally frozen--no response to keyboard or mouse, no
display of the stuff inside the frame.  Killing the R process didn't
help.  I had to kill my whole emacs session.

Maybe some configuration info is relevant.
Running Debian GNU/Linux, basically testing (just a hair beyond the
recent release).  
emacs21              21.4a-1 
r-base-core          2.1.0-1
kdelibs              4:3.3.2-6.1
xserver-common       4.3.0.dfsg.1-14

I do seem to recall having error=recover work OK in ESS fairly
recently..
