The artifacts don't look like typical radiosity artifacts to me. Maybe 
specks of light reflected off the green glass inside the lantern and 
then out through one of the holes?

If it wasn't for the render time I would suggest trying the same scene 
with the holes in the lantern patched up.

That said, using small emissive objects as illumination sources in 
radiosity scenes is a typical settings to get stray bright speckles; I 
would recommend making the flame object invisible to radiosity (using 
the no_radiosity keyword), and placing a regular light_source there.
