Description of problem:

zenity lacks the --html option, probably needs to compile zenity with WebKit. 

Version-Release number of selected component (if applicable):

zenity 3.8.0

How reproducible:

always

Steps to Reproduce:
1.Try this command from a terminal window

echo "hello world" | zenity --text-info --html --filename=/dev/stdin

2. It fails with the following message:

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

3. But without the option --html it works (displays a window with 'hello world')

Actual Results:  
zenity fails in opensuse and fedora, but works in several other distros.

Expected Results:  
success, so that html formatting can be used with zenity --text-info

Additional info:

--html option uses WebKit to render. Probably zenity wasn't compiled with
WebKit, so the option doesn't exist.

Please try to solve the problem by compiling zenity with WebKit!

I had the following mail conversation with a developer/maintainer of zenity, Arx Cruz:

Hello

--html option uses WebKit to render. Probably zenity wasn't compiled with WebKit, so the option doesn't exist. You need to open a bug against the distro to compile zenity with WebKit.

Kind regards

    Hi Arx Cruz,

    *Background*

    I found your name at https://wiki.gnome.org when looking for information
    about the --html option in zenity --text-info

    I use zenity in 'mkusb' version 9 described at

    https://help.ubuntu.com/community/mkusb

    This command (in a bash script) was developed in Ubuntu and works in
    several distros, for example Debian, Knoppix and Mageia Gnome:

    in the mkusb script:

    (echo "$htmlbody") | zenity --text-info --html --filename=/dev/stdin \
    --height=$(($hadd+120)) --title "" --timeout 2 2>> "$errout"

    for testing from a command line:

    echo "hello world" | zenity --text-info --html --filename=/dev/stdin

    But in Fedora and openSUSE, it fails. It seems to me, that the --html
    option is missing.

    I use the --html option to enable colours, text control and graphics.

    1. Red background for a final warning before flashing an iso to a device

    2. For better control of the text

    3. For graphics - the mkusb logo icon and an arrow

    *Question*

    Is it correct, that the --html option is missing? Or is it something
    else that makes it fail?

    *Details*

    Ubuntu 12.04.5 LTS uses zenity version 3.4.0
    Ubuntu 14.04.1 LTS uses zenity version 3.8.0
    Knoppix 7.4 (the current version) uses zenity version 3.12

    and they all work.
    -----
    Fedora 20-GNOME uses zenity version 3.8.0

    Fedora-Live-Desktop-x86_64-20-1.iso

    and fails with the following message:

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

    It works without the --html option
