Hi,

A check should maybe be added to verify that the icon specified in the
.desktop file exists in the hicolor theme in png format.

For example mutt sets the Icon key in its .desktop file but ships no
.png file in the hicolor theme. With gnome-shell it fallback to the .xpm
icon. (see: #854132)

A check could also verify that a big enough icon for nowdays standards
(48x48?) is provided.

Hi Laurent,

Could icons ship in a separate, architecture-independent package while
the desktop file is created from a template when the binary is build,
and may thus vary by architecture?

Some relationships may be hard to track, although Lintian can see them
if both installation (deb) packages were built from the same sources.
Are there icon sets that are maintained separately for the benefit of
other projects?

How about an info tag if a package's desktop file relies on external
icon resources?

Kind regards,
Felix
