Bug#802338: firmware-linux-nonfree: fails to upgrade from 0.44 (Missing Replaces/Breaks headers in firmware-misc-nonfree and firmware-amd-graphics?)

[Axel Beckert <abe@debian.org>]

Package: firmware-linux-nonfree
Severity: serious
Version: 20151018-1

Hi,

there seem to be Replaces and Breaks header missing in
firmware-misc-nonfree and firmware-amd-graphics for moving files
around since 0.44. This breaks the upgrade of firmware-linux-nonfree
from 0.44 to 20151018-1:

Since all three packages come from the same source package I decided to
report it against that binary package which involves all three instead
of filing two separate bug reports against firmware-amd-graphics and
firmware-misc-nonfree.
