The cluster replication verifies blocks by pulling them in batches, and performs hash chain verification + verifies the signatures of the last block in the chain. It uses the bundle stored in the global config structures, but in case it comes across a config block in the middle of the batch, it switches to use a bundle constructed from that config block. However, if the config block is the last block in the batch - it accidentally verifies it twice: - once with the config block before it (as expected) - once with the config block itself (which is unexpected). This change set simply adds a check to see if the last block in the batch is a config block, and if so - doesn't verify it if it was already verified.
