Hi,

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


Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> # otherwise rustc gets an empty multifile which lintian errors on, causing
> # FTP auto-reject. this is a work-around, the lintian bug is #955752
> # double up the max entries count, else the build might fail..
