back-sql: custom attribute list: segmentation fault

Hi all,

I'm using OpenLDAP (2.2.6) with back-sql and postgresql (7.3.4).
My LDAP tree structure is very similar to the back-sql example. There is one root dcObject (dn: dc=panline,dc=net). Trying JXplorer (a Java LDAP GUI browser) and performing a simple search I have caused the slapd server to segfault. I have found that

ldapsearch -b "dc=panline,dc=net" "(&(objectClass=*)(gecos=test))"

works fine, but

ldapsearch -b "dc=panline,dc=net" "(&(objectClass=*)(gecos=test))" gecos

causes slapd to segfault. I started slapd in debug mode and perform the second ldapsearch. I have noticed that
it tries to obtain the custom attribute list for object with dn=dc=panlne,dc=net and segfaults.
Is there any limit in constructing ldapsearch with back-sql or I have inserted some bad data within ldap meta data?
Any help would be very appreciated! Thanks in advance
