I have written a Python application (with pygtk and pymozembed) which I use very often.

In the Unity dash my application has an icon (as I definded in the .desktop file). But when I start it, there is no icon in the launcher. Just an empty hole.

Launcher file: /home/witek/.local/share/applications/kadro-reader.desktop

[Desktop Entry]

Name=Google Reader

Comment=Open site with Kadro: reader -> https://www.google.com/reader/view/

Icon=/home/witek/.kadro/sites/reader/icon.png

Exec=/home/witek/.kadro/sites/reader/start.sh

Categories=Network;

Type=Application

Python code for window initialization:

win = gtk.Window()

win.set_title("Google Reader")

win.set_icon_from_file("/home/witek/.kadro/sites/reader/icon.png")

How to add an Unity launcher icon to my Python application?
