Hello, jabłko, Thanks for the details. The problem was found on our Lucid build- servers, so this is still a problem there.
However, knowing that the problem is fixed in some particular version lets us backport the particular package. I am not sure if anyone will bother with backporting the fix to lucid?

I am using nss-updatedb to get user information from LDAP and I am using nsswitch.conf with the 'db' backend. Everything was fine until I tried to setup quota on one of the machines. edquota segfaults. I changed the backend to 'ldap', and this worked so this showed that the problem is in libnss-db.
