slapd dies with this error:

slapd: dn.c:946: dnMatch: Assertion `!((value)->bv_val == ((void *)0))' failed.

AFAICS this happens when syncrepl tries to read an entry which has an empty 
uniqueMember attribute.

This minimal LDIF-file triggers this bug:

----
dn: o=myOrganization,c=DE
objectClass: organization
o: myOrganization
structuralObjectClass: organization

dn: cn=tst,o=myOrganization,c=DE
cn: tst
uniqueMember: cn=user1,o=myOrganization,c=de
uniqueMember:
uniqueMember: cn=user3,o=myOrganization,c=de
objectClass: top
objectClass: groupOfUniqueNames
structuralObjectClass: groupOfUniqueNames
----

Thanks in advance
