Looking at the contents of /var/lib/dpkg/info/tirc.prerm, it contains the follwoing bit of shell code:

  if [ \( "$1" = "upgrade" || "$1" = "remove" \) -a -L /usr/doc/$pkg ]; then
    rm -f /usr/doc/$pkg
  fi

Unfortunately, while || is valid for or'ing the result of two programs,
it does not work inside of a test/'[' statement; -o needs to be used
instead; i.e. the code needs to be changed to:

While tirc has been dropped from intrepid, I noticed this in
a test upgrade from hardy to the intrepid beta.
