What version of BerkeleyDB did you have before, and what version did
you upgrade to? (Not that knowing that is likely to help us solve
this mystery, but I'd still like to know.)

Instead of 'svnadmin recover', have you tried using Berkeley's native
'db_recover' utility, passing it the '-c' option, meaning "perform
catastrophic recovery"? Make sure nothing else is accessing the
repository when you do it.

(See http://www.sleepycat.com/docs/utility/db_recover.html.)
