Error with substitution of a Complex{Float64} value in polynomial with complex coefficients

[Paul-Roux-Phys]

Hi, thanks for the great package!

Here is my problem ; when I try to substitute a complex value in a polynomial with complex coefficients, I get an error

julia> using Symbolics
julia> @variables x
julia> p = 0.4 + 1.7im*x
julia> substitute(p, Dict( x => 0.2 + 1.0im))

Am I doing something incorrect, or is this a bug ?
