System problem detected

[Richard Kimber]

After completing the upgrade to 19.04, I get a window indicating that
a system problem has been detected. It doesn't indicate what the
problem might be but just offers the option to report it, which I've
done.

How might I best find out what the problem is? I assume there's
something in syslog, but I'm not clear what to look for.
