bdb 4.6 issue with 2.4.12

[Guillaume Rousse <Guillaume.Rousse@inria.fr>]

Since I upgraded one of my server from 2.4.11 to 2.4.12, I'm facing 
heavy database issues:
[root@etoile ~]# slapcat -b dc=msr-inria,dc=inria,dc=fr
...
bdb(dc=msr-inria,dc=inria,dc=fr): pthread lock failed: Invalid argument
bdb(dc=msr-inria,dc=inria,dc=fr): PANIC: Invalid argument
bdb(dc=msr-inria,dc=inria,dc=fr): PANIC: DB_RUNRECOVERY: Fatal error, 
run database recovery
bdb(dc=msr-inria,dc=inria,dc=fr): PANIC: fatal region error detected; 
run recovery
bdb_db_close: database "dc=msr-inria,dc=inria,dc=fr": close failed: 
DB_RUNRECOVERY: Fatal error, run database recovery (-30975)

Even importing a backup ldiff file on a fresh installation triggers the 
same problems.

I tested this problem on two different environment (mandriva 2008.1, 
mandriva cooker), and one user reported it against mandriva 2009.0 
(https://qa.mandriva.com/show_bug.cgi?id=45034). This seems to either 
imply an openldap or a packaging issue. Should I report an ITS for this, 
or rather provide more informations ?
