[buildd-tools-devel] sbuild and build-depends-arch, troubleshooting

[peter green]

I run a debian-derivative called raspbian. On our autobuilders sbuild 
fails to install build-depends-arch which causes mplayer to fail to build.

http://buildd.raspbian.org/status/fetch.php?pkg=mplayer&arch=armhf&ver=2%3A1.2-1&stamp=1447679686

Any idea what could be going wrong? I'm running sbuild 0.65.2-1which 
according to my googling should support build-depends-arch. I have 
checked that build-depends-arch appears in the "Sources" file in our 
repository.
