Why did you run into this issue now? The version above has been in
Debian oldstable since almost a year, are you sure you diagnosed this
for the correct package version?

This is the first bug report on this. It might affect other packages,
but there is no evidence of that yet. Also I am a little bit confused
on what is the actual error here.

Could you provide me the exact commands I should run in e.g. a Docker
container with Debian Buster to reproduce the bug? If I can reproduce
it, I should be able to get to the bottom of it.
