[Sugar-devel] Issues loading datastore objects

[Daniel Narvaez]

That fails with the following trace here, which is 2 in my list of issues.

dbus.ByteArray('2013-09-10T14:34:23.986468', variant_level=1),
dbus.String(u'mime_type'): dbus.ByteArray('text/plain', variant_level=1)},
signature=dbus.Signature('sv'))

So we have both normal strings and binary data wrapped in a dbus.Array and
no way to know which is which.

I tend to think we should base64 encode all the values (we could skip
dbus.String but I'm not too sure we would save bytes, because then for each
value we need to tell which type it is). Then on the js side we can
window.atob() all the values. To be honest I don't understand exactly what
atob returns but whatever it is, it can be used as a string and it can
transformed into a byte array (https://gist.github.com/borismus/1032746),
so we should be fine.
