That was mine.  I don't know if it will help, but you could try this
version:

function cleanpath {
  local var="${1:-PATH}" oldpath newpath=: entry
  oldpath="${!var}:"
  while [ -n "$oldpath" ]; do
    entry="${oldpath%%:*}"
    oldpath="${oldpath#*:}"
    case "$entry" in /*)
      case "$newpath" in
        *:"$entry":*) ;;
        *) [ -d "$entry" ] && newpath="$newpath$entry:";;
      esac;;
    esac
  done
  newpath="${newpath#:}"
  eval "$var"'="${newpath%:}"'
}

Is that backslash really there?  It will probably not do what you
want, although it shouldn't cause a segfault.
