Please update to the latest. Your issue mentions 1.0.0, but you are actually
using the guacd, etc. from 0.9.9, which is six releases old (over three years).
This looks like a duplicate of GUACAMOLE-257, which was fixed in
0.9.13-incubating.

> Reporter: Lukas Krempler
> Priority: Minor

> There are no troubles in the functions of guacamole. But there are some log
> entries in our syslog file:
> hostname kernel: [790049.145417] guacd[4661]: segfault at 78 ip
> 00007f70a34fee99 sp 00007ffe7fda2b50 error 4 in
> libguac-client-vnc.so.0.0.0[7f70a34f4000+f000]
> hostname guacd[4661]: Client disconnected
> The SSH and VNC connections are working without any problems.
> It seems that the segfault occurs on a client disconnect.
