You are getting this message when Octave tries to write the history
file and it fails because of permission problems.  I already fixed the
problem the development sources.  Now I see this:

Will octave3.2 return 0 back to the shell (as did 3.0?)

$ ( ( echo version | octave3.0 >/dev/null) ; echo $? )
error: Permission denied
0

$ ( ( echo version | octave3.2 >/dev/null) ; echo $? )
error: Permission denied
terminate called after throwing an instance of 'octave_execution_exception'
panic: Aborted -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete

Thanks for taking care. Do you by any chance remember the changeset or
which file to look at? I glanced over the last 100 Mercurial changeset,
but saw nothing obvious.

I think it was this change:

  http://hg.savannah.gnu.org/hgweb/octave/rev/deb668d53e60

Unless I'm missing something, I think this should be safe for 3.2.x.
