Yes, and in this case the error is printed to stderr and the headless
builder returns with a non-zero exit code.

The point of the headless build is that it doesn't itself reference
plugins which need to invoke UI code. If the runtime is capable of
displaying dialogs then I guess that will continue to work.  I've also
noticed that if you have UI plugins installed in your product which
are invoked at early-startup, you may get errors if there's no UI
available. But there's nothing we can do about this...
