connection error

[Ed Campbell <ja...@MadisonCounty.net>]

I have installed guacamole from the git repository, but am getting an 
error.  I had tried installing from source code, but didn't have much 
luck with that either.

The login is successful, then immediately disconnected.

My system is Linux Mint 17.3 KDE.
settings are as follow:

*_guacamole.properties:_*
guacd-hostname: localhost
guacd-port: 4822
user-mapping:    /etc/guacamole/user-mapping.xml

I am stumped.  I notice the segfault in the syslog, but have no idea 
what to make of it.  Also, doesn't seem to be an issue insofar as 
connecting is concerned, but the ownership and group in guacamole.war 
--should that be something other than root?

Need more info?  Just let me know what.

Thanks in advance for your assistance.
