Heh, I expected enough :)

Yup, that fix is basically what I've done in git, along with a few
more. The basic problem is in DBus, which has not yet committed the
patch needed for 'maybe' support, which would allow us to have empty
strings, rather than the "" hack. The reason it worked before was that
dbus-glib automatically converted a NULL string to "" in a workaround,
and so applications didn't have to do anything special.

See https://bugs.freedesktop.org/show_bug.cgi?id=27857 for the DBus
patch, and until that's committed we'll have to play the ""-type
games.
