Fail to start if port not available or not a high port

[deluge@vigor.co.za]

When is loaded it the first time, the config questions started. I selected port 80 and the rest and the client was gone.

Same after selecting port 2444 used by another application.

There should at least be a little dialog explaining why Deluge is about to disappear without a trace before closing due to a network problem.

It also took a while to find the config under .config/Deluge to get the config questions to be asked again.

1.x picks a random port if no port is available.
