Currently webbrowser.py only trying to use GNOME and KDE default browser
setting. This patch adds launching Xfce default browser if xfce environment detected.

This is a three line patch.

I'm not so keen on the os.popen() -- is there no other way to find out if XFCE is running?

[merwok]

Gajim lists processes thanks to /proc, which is platform-specific; a Web search shows the use of pidof, to the same effect; I looked for an envvar (I use Xfce) and found nothing.

[birkenfeld]

Closing to due to lack of a better way to detect Xfce.

[merwok]

Sorry I did not comment earlier, but there is this way:

>>> os.environ.get('DESKTOP_SESSION') == 'xfce'
True

[tiran]

I have a box with Ubuntu 12.04 and XFCE4:

declare -x XDG_CURRENT_DESKTOP="XFCE"
declare -x DESKTOP_SESSION="xubuntu"

I don’t understand what your message is saying, Christian.
