This is just how the build ends, not necessarily the relevant part.

It also fails here:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/libqapt.html

where you can get a full build log in case you need it.

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

Note: libkf5kipi has a similar bug.

Thanks.
