[SailfishDevel] Sending SMS via Telepathy: Error "Channel Dispatcher .. does not support interface CD.I.Messages"

[christopher . lamb]

Hi all
I am revisiting a Sailfish OS app that I have not touched for over a 
year!

Despite many Sailfish updates in that time, most of it still worked, 
apart from its most important function: sending SMSes.

The SMS functionality was achieved by a few lines of C++ calling 
Telepathy. The code is at the bottom of this post.

I now get the error
[D] TelepathyHelper::onSendMessageFinished:72 - Error sending message: 
"org.freedesktop.Telepathy.Error.NotImplemented" - "Channel Dispatcher 
implementation (e.g. mission-control), does not support interface 
CD.I.Messages"

I am a little stumped by this: At the moment I guess either something in 
Telepathy /used by Telepathy has changed. or I am missing a library that 
was previously on the Jolla (perhaps installed by me).

Any ideas?
