Suggested patch to correct the issue.

Change is basically to keep the 'source_database' as a string and only convert it to a byte stream in the method services.add_database_name.

There are some additional calls to ibase.b(database) which should probably also be changed, the ones I noted are in:

get_limbo_transaction_ids
_resolve_limbo_transaction
commit_limbo_transaction
rollback_limbo_transaction
get_statistics
nbackup
set_default_page_buffers
set_sweep_interval
set_reserve_page_space
activate_shadow
shutdown
bring_online
sweep
repair
