Thanks.  Actually some of these are incorrect, so I've applied a patch
that fixes the correct part and have removed the incorrect code.

This entire block is stale code I think.  If self.dialog_mode is "ppd",
self.device.id is definitely unset (we only created self.device a few
lines above).

No, that's not right.  The reason is that the getDevices() call
immediately above these new lines is asynchronous.  The reason we're
calling getDevices() at all here is precisely in order to get the Device
ID for the device we're changing the PPD of, because we don't already
have it.

Here's the patch that fixes the problem.  Another patch is in master
that removes the stale code.
