Status in “apparmor” package in Ubuntu: Fix Released
Status in “apparmor” source package in Hardy: Triaged

Bug description:
Binary package hint: apparmor

Impact: Lack of a single AppArmor base profile rule renders glibc unable to perform functions on Hardy that are available on Lucid.
Patch: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/668479/+attachment/1716210/+files/apparmor_2.1%2B1075-0ubuntu9.3.debdiff
Reproducing: trapping a segfault fails; see http://ubuntuforums.org/showthread.php?p=10043474
Regression potential: none known

Attempt to catch a SIGSEGV inside OpenLDAP on Hardy results in an AppArmor error message instead:
