These bugs will subsequently be closed (after merging), version set to
8+8.15rc3.dfsg.1-1, as they are fixed in Etch and Sid since upstream 8.15rc2
merged the fixed KRGB patch.

Severity is grave, as the KRGB problem hoses all printing in IJS devices
(which are really, really common) that use an 1-bit black channel (like all
monochrome ones, etc).
