Bug#827020: mumble: build-depends on libzeroc-ice35-dev which is no longer built

[Emilio Pozuelo Monfort]

Source: mumble
Version: 1.2.15-1
Severity: serious

Your package build-depends on libzeroc-ice35-dev but that package is no
longer built by src:zeroc-ice. You should probably build-depend on
libzeroc-ice-dev now.
