ERROR: DimensionMismatch("index 1 has size (300,), but size(A) = ()")

[grero]

I'm having trouble creating a ModelFrame in julia-0.4.0-dev+5194. I'm using the latest master of both DataFrames and DataArrays
Below is a toy example reproducing the error

using DataFrames
df = DataFrame()
df[:counts] = 50*rand(300)
df[:tlabel] = rand(1:8,300)
df[:dlabel] = rand(1:8,300)
f = counts ~ tlabel + dlabel
mf = ModelFrame(f, df)
ERROR: DimensionMismatch("index 1 has size (300,), but size(A) = ()")

The problem is with indexing of DatArrays.

data=DataFrame(X=[1,2,3],Y=[2,4,7])
data[:,1]

give the sam error, namely

julia> data[:,1]

While this work:

DataArrays._getindex(data[:X], Base.to_index([1], [1]))

this does not work

DataArrays._getindex(data[:X], Base.to_index([1,2], [1]))

Works on latest master.
