Pkg.dependencies crashes app executable

[schlichtanders]

I'm unable to create a functioning app that uses Pkg.dependencies()

Recreating the error
Generate a package with Pkg as a dependency:

julia> using Pkg
julia> Pkg.generate("MyPackage")
pkg> activate MyPackage
pkg> add Pkg

Edit MyPackage/src/MyPackage.jl:

module MyPackage
export julia_main
using Pkg

function julia_main()::Cint
    @show Pkg.dependencies()
    return 0
end

end # module

Make an app:

pkg> activate --temp
julia> using PackageCompiler
julia> create_app("MyPackage", "Compiled", incremental=true)

The app compiles successfully, but running it returns the following error.

$ Compiled/bin/MyPackage 
expected package `Pkg [44cfe95a]` to exist in the manifest (use `resolve` to populate the manifest)
