Description of problem: An AVC denial occurs when the "Add Printer" button is pressed in the CUPS web administration interface (http://localhost:631/admin) after logging in as root. Version-Release number of selected component (if applicable): selinux-policy-3.6.12-50.fc11 How reproducible: Every time Steps to Reproduce: 1. http://localhost:631/ 2. "Administration" tab at top 3. "Add Printer" 4. Log in as root Actual results: AVC denial Expected results: setroubleshoot shuts up Additional info: The following is from setroubleshoot: Summary: SELinux is preventing python (hplip_t) "read" security_t. Detailed Description: SELinux denied access requested by python. It is not expected that this access is required by python and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

Also occurred when selecting "Add Printer" in system-config-printer. It appears to happen during the process where it scans for new printers.
