Your catalog contains the missing object

The second is the one shown in your traceback above.

This means: the "OOBucket" with oid "0x25506" contains

Load it from the ZODB. Determine which keys belong to
the broken references and delete these keys.

You can fix them all as shown above.

While the "POSKeyError"s will go away, you have (of course)
lost information.
