"Trace/breakpoint trap (core dumped)" when running "unity-webapps-runner" without any parameters or arguments

I have recent found that I run "unity-webapps-runner" just by itself with no parameters or arguments that this is the output I get:

Due to some issues with apport I was unable to report the crash the standard way, but I have attached the core dump. This was in an Ubuntu 16.04 64-bit VirtualBox VM.
