Here is a failed build log:


https://build.opensuse.org/package/live_build_log/home:mike-fabian/ibus-typing-booster/openSUSE_Tumbleweed/x86_64

It fails with:

But the screenshots exist, emoji-picker.appdata.xml contains:

      <caption>Emoji Picker screenshot</caption>

and typing-booster.appdata.xml contains:

The screenshot files in these xml files do exist.

*And*, because the --no-net option is given to `appstreamcli validate`, the
checks needing network should not be done at all.
