New update is not working on Julia v.0.4

[randy3k]

I cannot identify the issue, it seems it has something to do with IJulia.jl. But I cannot figure it out. I am running the nightly build on Mac OS via command line.

PS: it is working on v.0.3.7

This appears to be due to JuliaLang/julia#8051.

I'll push a fix that can avoid this problem,
