You set the icon-name property.  This expects an icon *name*, not path,
to be automatically searched in configured the icon directories.

If you want to manually load the icon, you need to set the "logo"
property of type GdkPixbuf, so you need to load it manually.

The other (recommended) solution is to install your application icon in
a standard directory, or add your application's specific icon directory
to the icon search path, and set the "logo-icon-name" property to the
basename of the icon (e.g. without path or extension).
