Can you run 'svnadmin verify' on the repository? You're likely to get
the same error. If so, then you may be the first person I've met who
can consistently cause this fsfs corruption error. Changing to
mpm-prefork makes the issue go away, but I'm not entirely sure why.

Is there anything else special about your setup? A latent or lossy link
to the repository? What kind of machine are you hosting the repository on?
