Created attachment 937347 [details] screenshot of what it looks like in software center As the attached screenshot demonstrates, GNOME Software center shows an unofficial and outdated screenshot of Pitivi in Fedora 20. I'm not sure why that is, because the appdata xml file points to http://www.pitivi.org/i/screenshots/software_center_main.jpg
Closing. Should be fixed once Richard rebuilds the metadata. I'll ask him to do it on Tuesday.
