Comment 2 Christopher Beland 2009-07-17 16:21:05 UTC 
This bug is currently marked as affecting Fedora 8; if that is accurate, then you will need to upgrade to Fedora 10 or 11 (8 is no longer supported).  The "el5" in nagios-2.12-6.el5 indicate Enterprise Linux 5.  If you are running Fedora, you'll want to run a version which has been built for Fedora (in which case "rpm -e nagios" and then "yum install nagios" should work, if you are running a recent version of Fedora).  The latest version is 3.0.6-3.fc11, which may have already fixed this problem.

If you are running Enterprise Linux, you'll want to change the Product and Version this bug is filed against.  Thanks!
