reassign 314461 libnss-ldap thanks Hi Marco,
Thanks for the report. I'm going to reassign this to the libnss-ldap package, since that's where the crash actually happens; perhaps the nss_ldap maintainer will have an idea what this is. Have you gotten any more of these mails since you filed the bug report?
