glue objects

Hi,
when adding a subtree object, it is occasionally not properly created,
instead only a glue object is created:

,----[ created glue object ]
| dn: o=xxxxx,dc=abook,dc=example,dc=com
| entryUUID: a3a1368a-a12f-102e-941f-adf8df1281f9
| creatorsName: dc=abook,dc=example,dc=com
| createTimestamp: 20100129143758Z
| entryCSN: 20100129143758.447642Z#000000#001#000000
| modifiersName: dc=abook,dc=example,dc=com
| modifyTimestamp: 20100129143758Z
| objectClass: top
| objectClass: glue
| structuralObjectClass: glue
| entryDN: oxxxx,dc=abook,dc=example,dc=com
| subschemaSubentry: cn=Subschema
| hasSubordinates: TRUE
`----

Part of the script to create this object with proper objectclasses and
attributes can be found here:

Any idea why an object with objectclass glue is created?
