Bug#797463: libavcodec-ffmpeg56: M-A:same package is broken by binnmu; please do a sourceful upload

[Gábor Gombás]

Package: libavcodec-ffmpeg56
Version: 2.7.2-2+b1
Severity: important

Hi,

The latest binnmu on amd64 made it impossible to install both the i386
and amd64 versions:

# apt-get install -t unstable libavcodec-ffmpeg56:amd64 libavcodec-ffmpeg56:i386 -o Debug::pkgProblemResolver=yes

libavcodec-ffmpeg56:i386 is already the newest version.
libavcodec-ffmpeg56:i386 set to manually installed.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libavcodec-ffmpeg56 : Breaks: libavcodec-ffmpeg56:i386 (!= 7:2.7.2-2+b1) but 7:2.7.2-2 is to be installed
 libavcodec-ffmpeg56:i386 : Breaks: libavcodec-ffmpeg56 (!= 7:2.7.2-2) but 7:2.7.2-2+b1 is to be installed
E: Unable to correct problems, you have held broken packages.

I've found some mails in the archives which indicate that this is a
known shortcoming of binnmu'ing a M-A:same package, and the only
solution is a sourceful upload.
