...but my "recent thumbnails" are "moving".... In other words, I can see GUI 
activity. Furthermore, if I look at syslog while I'm in the "recent connections 
list", I do NOT see disconnections, but I do see messages such as:

Jan 29 08:27:08 guacd[17456]: Server completed frame 80764106ms.
Jan 29 08:27:08 guacd[17456]: User confirmation of frame 80764106ms received at 
80764109ms (processing_lag=1ms)
Jan 29 08:27:09 guacd[17456]: Server completed frame 80765116ms.
Jan 29 08:27:09 guacd[17456]: User confirmation of frame 80765116ms received at 
80765119ms (processing_lag=1ms)
Jan 29 08:27:09 guacd[17456]: Received nop instruction
Jan 29 08:27:10 guacd[17456]: Server completed frame 80766126ms.
...and so on...

If I open more VNC connections and come back to the "recent list", I get even 
more of these messages.
In fact, the connections are closed only when I "log out" of the Guacamole 
portal.
And that's when I get my segmentation fault.
