Segfault on startup

[Bilge]

When starting ntpd it segfaults almost straight away. The configuration is the default that ships with Ubuntu 12.04.1 LTS.

[Serge Hallyn (serge-hallyn)]

Thanks for reporting this bug. It is a result of a lock in liblockfile. I will mark this bug a dup of bug 941968. I've also bumped the priority of that bug to high to hopefully get the proposed patch to fix it reviewed faster.
