It's an artifact of the way they were built. The inner and 
outer rims were made separately, and assembled after the inner 
rim had soundboard, pinblock, plate, and strings were 
installed. The two rims didn't necessarily nest together all 
that accurately, so there are gaps, particularly where there 
are tight curves. The photo shows something similar. In this 
case, the outer rim in the treble was leaning inward to a 
degree making it very difficult to remove the plate, so I 
wedged it out some to square it up and get clearance to 
reinstall.

I wouldn't worry about yours. If it were being rebuilt, I'd 
reinforce it, but otherwise not bother. It's not uncommon.
