+Subject: [PATCH] Update libcap-ng capability handling
+
+There is a change coming in libcap-ng-0.8.1 that causes gnome-keyring to
+not work correctly. The capng_apply function now returns an error if it
+cannot change the bounding set. Previously this was ignored. Which means
+now gnome-keyring exits when it shouldn't.
+
+The new patch adds troubleshooting info to the error message. And it checks
+to see if we have CAP_SETPCAP. If we do not, then we cannot change the
+capabilities so we just bypass the whole thing that was causing an error.
+On the setuid side, it now drops the bounding set and clears any
+supplemental groups that may be left over as an accident.
