I was pointed out to the following broken thumbnail: https://upload.wikimedia.org/wikipedia/commons/thumb/1/1e/Zevenhuizen_Moerkapelle_wapen.svg/375px-Zevenhuizen_Moerkapelle_wapen.svg.png
The commons image page is: https://commons.wikimedia.org/wiki/File:Zevenhuizen_Moerkapelle_wapen.svg
As you can see (hopefully) is that the thumbnail is not completely generated, only the bottom part. Not sure if this is a one off, or a more general problem.

Cannot reproduce locally with rsvg-convert -h 375 -f png -o Zevenhuizen_Moerkapelle_wapen.png Zevenhuizen_Moerkapelle_wapen.svg but I'm already on librsvg2-2.44.13-1.fc29.x86_64 (plus I guess we don't use rsvg-convert for this job).
We do use rsvg-convert, Stretch is on libsrvg 2.40.16-1. This is very likely to be something that would be fixed by a librsvg upgrade.
