Connecting to remote server with client crashes. Reproducible

[wdeconinck]

I have 2 bugs here.

• I have a remote server, but accidentally try to connect to "localhost", through the menu.
• I retry to connect to the correct remote server through the menu, but nothing happens. I can keep doing this but nothing happens --> bug 1
• I retry to connect through the root signal "connect to server" . The client crashes immediately before even showing any dialog to enter the server--> bug 2

in bug 2, the crash is with a segmentation fault. The trace is here:
