This bug was fixed in the package hannah-foo2zjs - 1:3

---------------
hannah-foo2zjs (1:3) unstable; urgency=medium

  * QA upload.
  * Switch source format to "3.0 (native)".
  * Do not ship the generated hannah binary, and the Makefile, and make sure
    to remove them on clean.
  * Drop the menu file, since hannah-foo2zjs already provides a .desktop file.
  * Use an install file to install all the files, using dh-exec to rename the
    files:
    - add a new executable hannah-foo2zjs.install file
    - add the dh-exec build dependency
  * Rewrite rule to use the dh sequencer.
  * Bump the debhelper compatibility to 10:
    - bump compat to 10
    - bump the debhelper build dependency to 10~
  * Switch versioned conflict to versioned break.
  * Cleanup hannah.pro.
  * Build the application with Qt 5: (Closes: #874903)
    - set the QT modules in the .pro file
    - switch the libqt4-dev build dependency to qtbase5-dev
    - set QT_SELECT=5 in rules, to make sure to build even when Qt 4 is
      installed too
  * Various improvements to the application itself:
    - reindent code
    - forward-declare classes, including only what needed, and where needed
    - do not hardcode the font, use the default one
    - use better QMessageBox APIs
    - create & lay out widgets in the right order
    - add a checkbox -> firmware mapping, so there is not a separate list for
      the latter
    - turn the "Mark all" from a checkbox into a button, and add also a new
      "Unmark all" button
    - switch from QStatusBar to QLabel for the status messages
    - disable the download button while downloading
    - set the "printer" icon for the application
    - harden the build with extra defines, and fix the code accordingly
      (slot -> Q_SLOTS, QStringLiteral, etc)
    - group checkboxes & mark/unmark buttons in a group box, with the
      checkboxes laid in two columns
    - improve the text in the about dialog
    - add accelerators for buttons
  * Fix path of getweb to /usr/sbin/getweb. (Closes: #772447)
  * Use pkexec to run getweb, instead of su-to-root for the whole application:
    (LP: #1713311)
    - depend on policykit-1
    - drop the gksu|kdebase-bin|kde-runtime|kdebase-runtime|ktsuss|sux
      dependency (Closes: #885545)
    - directly exec hannah-foo2zjs in the desktop file
  * Make hannah.desktop file valid:
    - set the value of the 'Terminal' key to false (as it is a boolean)
    - add the Qt category, and remove the Settings one
  * Link in as-needed mode.
  * Bump Standards-Version to 4.1.3, no changes required.
  * Add myself to copyright, for both code and packaging.

  ************************************************************

  Steps to reproduce:
  1. Install Ubuntu 17.10
  2. Install application from above list and menu package (if missed, for zenmap, see bug 1713274) - full list from - https://codesearch.debian.net/search?q=Exec%3Dsu-to-root+filetype%3Adesktop+path%3A*%2Fapplications%2F*&perpkg=1 , https://codesearch.debian.net/search?q=Exec%3Dgksudo+filetype%3Adesktop+path%3A*%2Fapplications%2F* and https://codesearch.debian.net/search?q=Exec%3Dgksu+filetype%3Adesktop+path%3A*%2Fapplications%2F* .

  3. Try to launch $APP_NAME from shortcut
  4. Get error window:
  Failed to run $APP_NAME as user root.
  Unable to copy the user's Xauthorization file.

  Expected results:
  * $APP_NAME may be run as root

  Actual results:
  * unable to run $APP_NAME as root

  Additional info:
  $ xhost
  access control enabled, only authorized clients can connect
  SI:localuser:artful

  $ export | grep "SESSION\|DESK"
  declare -x DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus"
  declare -x DESKTOP_AUTOSTART_ID="1082dacfd3a20e972150382958079482700000012280008"
  declare -x DESKTOP_SESSION="gnome"
  declare -x GDMSESSION="gnome"
  declare -x GNOME_DESKTOP_SESSION_ID="this-is-deprecated"

  declare -x XDG_CURRENT_DESKTOP="GNOME"
  declare -x XDG_SESSION_DESKTOP="gnome"
  declare -x XDG_SESSION_ID="2"
  declare -x XDG_SESSION_TYPE="wayland"

  and this operations does not help:

  artful at artful:~$ xhost +si:localuser:root
  localuser:root being added to access control list
  artful at artful:~$ gksudo zenmap
  Error copying '/home/artful/.Xauthority' to '/tmp/libgksu-AgXCxW': No such file or directory
