Thanks.
It would be great if someone could make a backport of 2.5.1 for bullseye
(and/or fix the bug in 2.3.0+repack-2).

Fwiw, the tarball-in-tarball weirdness should be handled by
debian/uupdate.sh by simply invoking "uscan". Please let me know if
that doesn't work for you, then we need to fix that script not to rely
on my local build enviroment tweaks.

Thank you Benjamin.  For some reason this bug report ended up in my spam
folder and I didn't see it before my rebuild upload.  I am uploading a
build with the patch now and will also prepare an upload of 2.5.1.
