svnadmin: Missing node-id in node-rev

Running a svnadmin verify on my repository produces:

* Verified revision 7471.

* Verified revision 7472.

* Verified revision 7473.

svnadmin: Missing node-id in node-rev

This is what shows up when I view the bad changeset 7474 via TRAC:

SubversionException: ('Missing node-id in node-rev', 160004)

There are 3 changesets in a row (7474-7476) suffering from this problem.

We use BDB, and snvadmin recover doesn't help. Anyone have any thoughts on
how to recover?
