This doesn't look quite right to me at first glance... FSFS logical 
addressing was added in 1.9 and was certainly not available with format 
3 then. That might however just be an issue with the presented output 
not being correct rather than pointing to some actual issue.

I recall there' were some fixes related to some old repositories in 1.10 
(which is currently in RC2) but skimming quickly through it I didn't 
find a related note in the changelog directly.

Still, maybe worth a shot to see what svnadmin verify reports with the 
1.10-version. If you have a windows machine, there's a prebuild 1.10 
build available here [1] (disclaimer, I'm the maintainer/developer 
behind that one). I'd also have a prebuild 1.10.0-rc2 build lying around 
which hasn't been released yet, but I'd be able to make it available to 
you, if that helps.
