MethodError in animation.jl

[rcnlee]

This constructor:

function Animation(plt::PlottingObject)
  Animation(plt, mktempdir(), ASCIIString[])
end

seems to be throwing an error because mktempdir() returns a UTF8String while Animation is expecting an ASCIIString. Converting it fixes it:

function Animation(plt::PlottingObject)
  tmpdir = convert(ASCIIString, mktempdir())
  Animation(plt, tmpdir, ASCIIString[])
end
