Hints

• asv-url-not-secure
  org.gnome.Podcasts.appdata.xml:149 - http://www.gnome.org/friends/
  Consider using a secure (HTTPS) URL for this web link.
• asv-nonstandard-gnome-extension
  org.gnome.Podcasts.appdata.xml:142 - kudos
  This tag is a GNOME-specific extension to AppStream and not part of the official specification. Do not expect it to work in all implementations and in all software centers.
• asv-description-first-para-too-short
  org.gnome.Podcasts.appdata.xml:56 - Listen to your favorite podcasts, right from your desktop.
  The first `description/p` paragraph of this component might be too short (< 80 characters). Please consider starting with a longer paragraph to improve how the description looks like in software centers and to provide more detailed information on this component immediately in the first paragraph.
