I can reproduce it here with a known-good monotone instance
(near-current head), it seems that the server is sending
(valid) revision data which doesn't match the associated
revision_id. Someone else reported the same problem to the
list about a week ago.

(Also the netsync error handling isn't smart enough to know
it's not a 'bug in monotone' on the client side).

Could the server admin run "db check" and see if that shows
anything? (I've bcced him) It seems most likely to be bad
hardware or perhaps a strange miscompilation bug, though
could be a server-side monotone bug.

The revision in question seems to be the first revision of a
branch (no old_revision) and has a manifest_id of
785e7d8bed37af1bd14b4b4a6339b8437204011a.
