Hi,
rust-derivre 0.3.12-1 proudly declares in its debian/control:
Section: FIXME-(packages."(name)".section)
which leads to a dsc file containing
Package-List:
derivre deb FIXME-(packages."(name)".section) optional arch=any
librust-derivre-dev deb rust optional arch=any
I suspect that should be rejected earlier. You are in good company though,
the archive does not detect this either, and takes over the Package-List:
as a Binary tag into the Sources file -_- .
