What exactly do you mean by an empty db? I see:
 >>>
ada:~/OD/o24/tests> rm testrun/db.1.a/*
ada:~/OD/o24/tests> ../servers/slapd/slapd -Tc -f testrun/slapd.1.conf
bdb_db_open: warning - no DB_CONFIG file found in directory 
/home/hyc/OD/o24/tests/testrun/db.1.a: (2).
Expect poor performance for suffix "dc=example,dc=com".
bdb_db_open: database "dc=example,dc=com": 
db_open(/home/hyc/OD/o24/tests/testrun/db.1.a/id2entry.bdb) failed: No such 
file or directory (2).
backend_startup_one: bi_db_open failed! (2)
slap_startup failed
ada:~/OD/o24/tests>
<<<

Please provide steps to reproduce the segfault, thanks.
