This is the same bug reported in #847340 against initramfs-tools: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=847340
The problem is in initramfs-tools; firmware-misc-nonfree is just the trigger. Rather than merging, I would like to leave this bug against firmware-misc-nonfree to protect apt-listbugs users from the breakage upgrading firmware-misc-nonfree triggers.
