Bug#1086181: lintian: Many false positive warnings for appstream-metadata-validation-failed

[Peter B <peter@pblackman.plus.com>]

Package: lintian
Version: 2.119.0
Severity: normal
X-Debbugs-Cc: peter@pblackman.plus.com

Dear Maintainer,

Since the release of version 2.119.0, the package trackers for many 
(possibly all)
packages that have Appstream metadata are showing the warning
 "appstream-metadata-validation-failed".

However, the metadata is valid according to
"appstreamcli validate"  &  "appstream-util validate".

The link in the tag notes
  https://wiki.debian.org/AppStream/Guidelines
does not contain any clues as to what might be the problem here.

If these are not false positives,
please provide information on what maintainers are expected to do about 
them.


Appstream is an optional upstream feature.
Please consider introducing Appstream related tags at a lower severity 
than Warning.


Regards,
Peter
