At first I thought it was being deleted, but it does seem to reappear at a later point. I've not yet pinned down a repeatable sequence (or even 100% convinced myself I'm not imagining it).
> Next step would be to copy the messages and then delete from the modem (to avoid filling the me storage) - since the actual processing of them may take some time. I'd prefer to copy the whole Sms object rather than just, say, the text - what's a safe way to do that, across all eventualites?
So, I've been looking for a way to copy/clone a whole ModemManager.Sms, but haven't been able to find anything in the API (?), so I've fallen back on copying out the essential 'properties' instead.
I'm now deleting the messages [in the modem] after copying, and find that - in the start-up case - I also get a 'notify::messages' callback when *deleting* messages. Is there a way to examine deeper the detail of the notification?
