JLD 0.0 reader should convert data to field type

[tomasaschan]

I have a JLD file saved a few months ago, and a script which loads data from it and plots it. When I run the same script today, I get the following error:

type: setfield!: expected Dict{Symbol,Int64}, got Dict{Symbol,Union(AbstractArray{Real,1},Real)}
while loading In[4], in expression starting on line 6

The relevant section of my own code is this:

jldopen(joinpath(root, "processed.jld")) do f
    read(f, :sall), # <-- This is ReportPlots2.jl:28 in the stacktrace above
    read(f, :sloops),
    read(f, :sloss),
    read(f, :initialhist),
    read(f, :finalhist),
    read(f, :Nbins)
end

Is this a known problem? Can I get around it by changing my code somehow? The file processed.jld holds postprocessed data from a computation run that potentially takes the better part of a day to run, so it would be nice to not have to re-run it just because I can't read the file...

I've tried pinning the package to earlier versions, but without finding one that works (I get the same error with all the ones I've tried; unfortunately, I haven't taken notes what versions I've tried...).

Dup of #198. Should work on master.

Thanks a lot for the quick reply, @simonster!

However, I can't quite get it to work. After Pkg.checkout("HDF5"); Pkg.checkout("Compat"); Pkg.update(), then restarting the kernel and trying again, I still get the same error message. Any hints on what to try next?

[simonster]

Ah, I see now. Your JLD file is in the old format, and we only changed this for the new format. I'll see if I can tweak that to work as well.

(If you want this to work immediately, the easiest solution is to downgrade DataFrames to 0.5.12.)

I just need these files very temporarily (I have to make a few last fixes to my thesis report) and then hopefully I'll never need to read them again, so downgrading is definitely an option. Thanks for the version reference (and for the very quick response!) - I could get it working now! =)
