New appstream data has weird screenshot URLs

This is how it looks in debugger (needless to say this URL returns 404 and no screenshot is displayed)

FTR this weird URL with addition of some base (?) URL comes directly from underlying libappstream (AppstreamQt), no one is manually appending anything in plasma-discover code!

However, metadata XML for org.kde.ktorrent screenshots looks innocent:

<screenshot type="default">
      <image type="source">https://cdn.kde.org/screenshots/ktorrent/ktorrent.png</image>
      <image type="source" width="766" height="541">org/kde/ktorrent.desktop/214435abe2b8d85089dc352adbfb4873/screenshots/image-1_orig.png</image>
      <image type="thumbnail" width="752" height="531">org/kde/ktorrent.desktop/214435abe2b8d85089dc352adbfb4873/screenshots/image-1_752x531.png</image>
      <image type="thumbnail" width="624" height="440">org/kde/ktorrent.desktop/214435abe2b8d85089dc352adbfb4873/screenshots/image-1_624x440.png</image>
      <image type="thumbnail" width="224" height="158">org/kde/ktorrent.desktop/214435abe2b8d85089dc352adbfb4873/screenshots/image-1_224x158.png</image>
</screenshot>

Thumbnails screenshots load fine now though. Issue seems to affect only the first "source" url which starts with https://
