assertion failed: :((typeof(pop_event(composer))==StreamStartEvent))

I'm getting that assertion on pretty much everything:

julia> import YAML

julia> YAML.load("../settings.yml.default")
ERROR: assertion failed: :((typeof(pop_event(composer))==StreamStartEvent))
 in compose at /Users/keno/.julia/YAML/src/composer.jl:37
 in load at /Users/keno/.julia/YAML/src/YAML.jl:21
 in load at /Users/keno/.julia/YAML/src/YAML.jl:40

julia> YAML.load_file("../settings.yml.default")

 in load_file at /Users/keno/.julia/YAML/src/YAML.jl:46

The yml file:

worker_port:    8000
docker_host:    127.0.0.1:4243

This was working a few days ago. It seems to be a Julia bug, but I can't figure out what's causing it. Filed here: JuliaLang/julia#3807

Alright, I'll see if I can tackle the Julia bug.
