I came across an issue when re-connecting a session. I am using a VNC over SSH session, and if the session gets disconnected for whatever reason, Remoter gives a message that the session is disconnected, and do you want to reconnect? If you click yes, Remoter will attempt to connect, but is not able to. I only see the little window with a Cancel option. If I click Cancel, then Remoter crashes.
The easy way to replicate it is to connect to a VNC session, then kill the VNC server causing the Remoter session to be terminated. Click Yes, to re-connect, then click Cancel.
