Doesn't seem to work:

reply = device_iface.call("DriveEject", arg)
print(reply.errorMessage())
Returns:
Unknown option
....because "" is not a valid option? According to...
http://hal.freedesktop.org/docs/udisks/Device.html#Device.DriveEject
...."unmount" is the only valid option.

Indeed it does work as:
arg = QtDBus.QDBusArgument()
arg.beginArray(QMetaType.QString)
arg.add("unmount")
arg.endArray()
and so does:
arg = QtDBus.QDBusArgument()
arg.beginArray(QMetaType.QString)
arg.endArray()
Experimenting with other calls shows this is the way to create an empty
Array of Strings.
