BoundsError: attempt to access (1,0,true) at index [4] in the draw function

[cyocum]

I am attempting to output a PCA plot in Gadfly 0.4.1 using the following code:

 pca_plot = Gadfly.plot(x=pca.proj[:,1], y=pca.proj[:,2], label=vec(header), Geom.point, Geom.label, Theme(background_color=colorant"white", panel_opacity=0))
 draw(SVG("pca-v4.svg", 24cm, 12cm), pca_plot)

I get the following error:

ERROR: LoadError: BoundsError: attempt to access (1,0,true)

I am using julia 0.5.0-dev version as 0.4.3 refuses to compile on Ubuntu.

This is actually an issue in Showoff.jl calling into unexported API's from base that were changed on master. Ref JuliaLang/julia#14723 and JuliaLang/julia#14623 (comment)

0.4.3 refuses to compile on Ubuntu.

You should address that first, julia master is unstable and you should expect packages to break. Release will be much more stable.
