Title:
  zenity's option to render html does not work

Status in zenity package in Ubuntu:
  Fix Released

Bug description:
  Zenity was updated a few days ago. Until then there was a bug with
  --checkbox, which is fixed now :-) But another bug was introduced:
  zenity's option to render html does not work. A similar bug was
  squashed in OpenSuse last year, and is still there in Fedora and
  Centos. But --html works in all versions of the Ubuntu flavours from
  12.04 LTS 'Precise' to 15,04 'Vivid', and worked in 'Wily' until this
  last update of/to zenity 3.16.3.

  The error output states:

  "This option is not available. Please see --help for all possible
  usages."

  The bug that was squashed last year was fixed in OpenSuse by compiling
  with WebKit. Maybe that works also now, maybe another tool is
  necessary now to add capability for html with the option --html.

  Arx Cruz knows which tool to use:

  "The --html is only available when you compile with webkit > 2.8.1 and
  the library is webkit2gtk. See
  https://bugzilla.gnome.org/show_bug.cgi?id=749798

  If the new zenity wasn't built with support to this, you won't see the
  --html option."

  You can run the following bash shell-script to test if it works or not.
  -----
  #!/bin/bash

  echo "<h1>HTML headline</h1>
  Hello World" | zenity --text-info --html --filename=/dev/stdin \
  --width=$(($wadd+640)) --height=$(($hadd+400)) \
  --title "$btitle" \
  --ok-label="Go" --cancel-label="Quit" \
  --checkbox="Check this box if you are ready to go"

  It should create a window similar to that in the attached file 'correct-rendering-html-precise.png'
