Going back to this problem - I rechecked everything - port was wrong. After correcting it,
I'm now having this problem:

Hopefully this will change when I get the postgresql going, but I only have the hostname,
port, and password in the file - I also tried ports 5900 and 5901 - both yield same error.

Hello Nick:

I can connect from another client over VNC - it is only asking for the password, so I don't
know what the user name is...Is the segfault issue part of the connection issue? If so, how
did guacamole ever work?


The vast majority of VNC servers don't require a username, just a password, so that makes
sense.  Make sure you're entering that password into the connection information for Guacamole.
 You shouldn't need a username.

I can't remember the exact details of the segfault, but seems like it happened when the password
was missing or incorrect (rather than displaying a warning), and maybe under some other set
of circumstances.
