Comment 17 for bug 273761

Yes, the libc6 crash on dpkg-reconfigure is the same bug; the libc6 postinst invokes "init u" which is segfaulting (on i686). It can also be reproduced by directly invoking "sudo init u" or "sudo telinit u". The apport crash-reporter only reports the first time it sees the same bug/crash. You can get apport to re-run by removing the existing crash file /var/crash/_sbin_telinit.0.crash and then triggering the bug again.
