Consecutive calls to 'dpkg --purge' gets the same error and no more
information.
Looking at /var/lib/dpkg/info/mt-st.postrm, I think it's due to:
if [ "$1" = purge ]; then
[ -L /etc/udev/rules.d/z60_mt-st.rules ] && \
rm /etc/udev/rules.d/z60_mt-st.rules
fi
if the file isn't a link or doesn't exist, the script returns with an
error code. With a proper 'if' statement, the problem should occur.
No - commands that are part of an && or || chain are excepted from
terminating 'set -e'-shell scripts even if they exit with nonzero status
(otherwise, there'd be little point in using these constructs - and the
I didn't know this, good to know, but it's not the point because the
above command is the last one in the script, which exits with the return
code of the command, i.e. 1 if the link doesn't exist.

If you're sure of this, then debhelper is wrong and you should forward
the bug to the package.
I have successfully patched the post-rm script by replacing the "&&"
construct through an "if" one, and the package purged flawlessly.
But it's easy to test: install mt-st, remove the above link and try to
--purge the package. I can reproduce it, see the end of the mail.
