as already written in that github bug, I'm unable to reproduce this problem.
Are you for example able to create a chroot and install and configure sbuild
from scratch inside that chroot and still reproduce that problem? I just want
to be sure that there is no external influence. By providing a step-by-step
instruction how to setup that chroot, we could eliminate that we are running
different configurations.

Thanks!
