I failed in a first attempt to reproduce the bug in roughly the same conditions as first posted but I will keep trying. I will (hopefully today) try with a kubuntu karmic live cd and report back.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Karmic Koala. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/. Thanks again and we appreciate your help. ** Changed in: ntp (Ubuntu) Importance: Undecided = Low ** Changed in: ntp (Ubuntu) Status: New = Incomplete ** Changed in: ntp (Ubuntu) Assignee: (unassigned) = Chuck Short (zulcss) -- SIGSEGV in ntpq https://bugs.launchpad.net/bugs/254375 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
