This doesn't happen in 100% attempts but more books in sync set = more probability to get this.
Plugin options:
debug logging:yes
update metadata:yes
sync threads:4 (and I would setup more if possible)
bookshelves column:#bookfusionshelf

Plugin's window can't be closed when this happens (it shows same error message)
