If you're simply having trouble establishing a connection to your VNC server at
all, please open a new thread on the mailing list rather than opening a new bug
report:
http://guacamole.apache.org/support/#mailing-lists
It is extremely unlikely that Guacamole has a bug so fundamental that
connecting to VNC servers over the network is completely broken, and the
mailing lists are the best place to request help with such things.

There is a known issue in 0.9.13-incubating and older which resulted in a
segfault upon disconnect. The segfault occurred due to an attempt to free
memory that was not actually allocated, and had no effect on connection
stability. This was recently fixed via GUACAMOLE-388 and GUACAMOLE-424.
Assuming this is what you're seeing here, it is not related to your current
difficulties in connecting.
