Crash on 0.5: MethodError: no method matching getindex

[staticfloat]

While trying to debug a BinDeps problem, I ran into the following:

julia> using Gallium

julia> include(Pkg.dir("Cairo","deps","build.jl"))

julia> @enter BinDeps._find_library(group)
In /Users/sabae/.julia/v0.5/BinDeps/src/dependencies.jl:706
705   function _find_library(deps::LibraryGroup, allfl = allf(deps); provider = Any)
706       providers = satisfied_providers(deps,allfl)
707       p = nothing
708       if isempty(providers)

About to run: (BinDeps.allf)(<suppressed 2530 bytes of output>)

This kills the Gallium session.
