Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.

The correct upstream has it fixed.

[JB VideoLAN (jb-videolan)]

Fixed in Debian.

[Benjamin Drung (bdrung)]

Fixed in libdvdnav 4.2.1-3 since Ubuntu 14.04 (trusty).

[Sebastian Ramacher (s-ramacher)]

This should no longer be an issue. The fixed handbrake version got synced to Ubuntu.
