The application icon is displayed in the About dialog window.
On Linux, in some desktops (WM running without DE), XDG_DATA_DIRS is not defined and get_icon_path() in util.py cannot find the application icon to be displayed in the About dialog window.
Solution: add a fallback application icon in /usr/share/pixmaps.
Add /usr/share/pixmaps as fallback icons path #14
Add '/usr/share/pixmaps' as a fallback icons path as suggested
on issue #14 when XDG_DATA_DIRS is not defined.
Now it should be fine
Yes it works. Issue can be closed.
However, there is a (slight) preference to have /usr/share/icons/hicolor/.../apps/ as default locations over /usr/share/pixmaps (http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html#install_icons). Not related to this issue: 48x48 is not one of the available icon sizes, but is the default fixed application icon size (for an application .desktop file on linux).
