JLD fails to load type Complex

[waTeim]

The following scenario

using HDF5,JLD
testFile = jldopen("test.jld","w")
c = 1 + im;
@Write testFile c
close(testFile)

and then later:

julia> using HDF5, JLD
julia> testFile = jldopen("test.jld","r")
julia> @READ testFile c

Results in the generic error

[timholy]

Thanks for the comprehensive report. Should be fixed now if you do Pkg.update().

[waTeim]

Reconfirmed fixed in 0.2.26 for me on retest both OS/X and Linux.
BTW, did you just fix this in 1 day?

[timholy]

Great, thanks!

Fortunately, this one wasn't too hard to fix.
