Inexact error on 0.5

[tlnagy]

I discovered the following code crashes on 0.5-rc3 when reworking the documentation (#879)

julia> using RDatasets

julia> using Gadfly

julia> plot(dataset("ggplot2", "diamonds"), x="Price", color="Cut",
            Geom.histogram(bincount=30, density=true))
Error showing value of type Gadfly.Plot:

Actually, this is due to #864.

[tlnagy]

This is different than #864, since the fix for that is included in RC3 and this InexactError is still present. @shashi @StevenGL
