Is the latest update (63.0.3239.84-0ubuntu0.16.04.1) still affected?
Could you please install the debug symbols for chromium (see instructions at https://wiki.ubuntu.com/Debug%20Symbol%20Packages#Getting_-dbgsym.ddeb_packages, you want chromium-browser-dbgsym) and run in a terminal to get a more complete backtrace?
