When removing the package, octave3.2's postrm file is run, which
(correctly) removes the empty directory /usr/share/octave/packages.
octave 3.6 is then installed and brings this directory with it. When
purging octave3.2 later, its postrm is run *again* and removes the
directory (which now belongs to octave 3.6).

I guess the best fix is to change octave 3.6 postinst file to recreate this
directory if it does not exist.
The good news is that we will not run again into this as octave 3.6
brings this directory with it.
