Yes, sure.
This means that you've deleted a user who was added as Cc watcher to
ticket 55767. As well this means a bug exists in shredder and I've
fixed it and released shredder 0.05.

The following query is more informative:
SELECT u.Name, txn.id txn_id, txn.Field, txn.NewValue, txn.ReferenceType,
txn.NewReference, t.id tid FROM Tickets t JOIN Transactions txn ON
txn.Type = 'AddWatcher' AND txn.ObjectType = 'RT::Ticket' AND
txn.ObjectId = t.id LEFT JOIN Users u ON u.id = txn.NewValue WHERE
u.id IS NULL AND t.id = XXXXX;

This query selects only transactions with problems. txn_id column in
the result will show you problematic Transactions and NewValue column
will show you ids of the users that don't exist anymore.

You can safely delete this transactions using the following query:
DELETE FROM Transactions WHERE id IN (xxx, xxx, xxx,...);

Also, you can select all such transactions from your DB:
SELECT u.Name, txn.id txn_id, txn.Field, txn.NewValue, txn.ReferenceType,
txn.NewReference, t.id tid FROM Tickets t JOIN Transactions txn ON
txn.Type = 'AddWatcher' AND txn.ObjectType = 'RT::Ticket' AND
txn.ObjectId = t.id LEFT JOIN Users u ON u.id = txn.NewValue WHERE
u.id IS NULL;

If amount of the transactions is too big then I could help you write
down a delete query that will delete all this txns.
