On Ubuntu 16.04 LTS and guac 0.9.13 I do find a number of these entries in the logs: "segfault at 10 ip 00007f70d4364e52 sp 00007f70d2d6cd50 error 4 in libguac-client-vnc.so.0.0.0[7f70d435c000+13000]" note that this hasn't presented with any other issues AFAIK, sessions run smooth etc and VNC 'freezes' when the internet connection dies or the remote side reboots.
i just apt updated and there is no update available to libvnc so I'm up to 16.04's current "0.9.10+dfsg-3build1" As far as the hotkey, I remember it just fine, but I have muggles using this and they can't seem to commit it to memory.
