I'm running Ubuntu 16.04 LTS with the latest Teamviewer host.
Every time I reboot and login to the X session on the console, teamviewer host does a core dump. I can relaunch it and it works but I need it to work the first time.
I have the same problem, running TeamViewer 12 on CentOS 6.9.
Today it didn't happen. last two days in a row it was a problem...
