One way to deal with this is to manually download the .deb file and 
extract the files list into /var/lib/dpkg/info/.

Something is stopping the post removal scripts in the dpkg info 
directory from running.

Try adding a simple "hello world" script to /var/lib/dpkg/info/, and 
check it runs. If not, the problem is directory-wide, perhaps something 
is mounted noexec?

Try adding "set -x" to reiser4progs.postrm in the same directory, to see 
what it's doing and where it's failing.

noexec is the only thing I can think of, or scripts using an interpreter 
that doesn't exist.

good luck,
