Hello Chris,
Thanks, I think I have tried that already but I'll make sure and try again
tomorrow, the computer is rendering now.
I did notice, after I posted my question, that adding just the tiniest bit
of (ambient) light seems to solve the problem, as if that bit of light
starts the "fire". It shouldn't be needed, should it?

Strange... no it shouldn't. Does the HDR show up in the preview?
A few more tips:
- make the dome's color black (illumination should do the trick, not color)
- also, put the skydome out of the GI level (don't simply apply the GI
shader to the root). The dome is an indirect light source, it doesn't have
to be GI shaded.
- watch out for HDR files with big luminance in small details, they can
cause noise and require extra-high raycounts. The same effect as a small
window in a dark room - typically very difficult GI scenes.
- inside the GI shader, go to shader Surface Finishing, to the first
Raytracer object and increase Randomness to, say, 30 (corresponding to
Raycount1). This makes the GI sampling dome wider and you get more even
illumination.
Good luck - I'd love to see your results some day,
Mark H
