Bug#857644: widelands: appstream metadata error: missing icon

[Fòram na Gàidhlig]

Hi all,

I am the person who created the Appdate file for Widelands.

The reason for the warning:

tag-missing           : <translation> not specified

is that after extensive RTFM at the time I had no idea how to specify
this, so I decided to ship my own and add the translations directly to
the xml nodes as per the spec. They are provided by the translators as
JSON and I then run a script to generate them both for appdata and the
.desktop file.

If there is a smarter way of doing, this, I'm all ears.

Cheers
