SELinux is preventing /usr/bin/gpk-dbus-service from 'read' accesses on the fichier /var/lib/PackageKit/desktop-files.db.

*****  Plugin catchall_labels (83.8 confidence) suggests  ********************

If vous souhaitez autoriser gpk-dbus-service à accéder à read sur desktop-files.db file
Then you need to change the label on /var/lib/PackageKit/desktop-files.db
# semanage fcontext -a -t FILE_TYPE '/var/lib/PackageKit/desktop-files.db'
where FILE_TYPE is one of the following: udev_var_run_t, chkpwd_t, gconfd_t, pulseaudio_t, textrel_shlib_t, restorecond_exec_t, xguest_t, bin_t, cert_t, openoffice_exec_t, chroot_exec_t, rpm_script_tmp_t, usr_t, application_exec_type, xauth_t, default_context_t, xserver_exec_t, public_content_rw_t, noxattrfs, hwdata_t, locale_t, nsplugin_exec_t, system_dbusd_var_lib_t, fonts_t, proc_t, user_fonts_t, usbfs_t, policykit_auth_exec_t, chrome_sandbox_exec_t, selinux_config_t, loadkeys_exec_t, bin_t, cert_t, httpd_user_ra_content_t, httpd_user_rw_content_t, fonts_cache_t, lib_t, man_t, mnt_t, user_fonts_cache_t, xguest_gkeyringd_t, nsplugin_config_exec_t, ld_so_cache_t, usr_t, user_fonts_config_t, xserver_tmpfs_t, iceauth_exec_t, iceauth_home_t, xauth_exec_t, xauth_home_t, abrt_helper_exec_t, auth_cache_t, sysctl_type, locale_t, cupsd_rw_etc_t, sssd_public_t, etc_t, ld_so_t, telepathy_domain, dbusd_exec_t, security_t, src_t, sysfs_t, user_tmpfs_t, shell_exec_t, gconf_etc_t, passwd_exec_t, policykit_grant_exec_t, system_cronjob_var_lib_t, iceauth_t, chrome_sandbox_tmpfs_t, policykit_var_lib_t, oddjob_mkhomedir_exec_t, user_tmp_t, cupsd_etc_t, tetex_data_t, krb5_conf_t, xguest_dbusd_t, readable_t, xdm_tmp_t, alsa_etc_rw_t, gconf_tmp_t, abrt_var_run_t, java_exec_t, pulseaudio_exec_t, shell_exec_t, chkpwd_exec_t, xdm_etc_t, hplip_etc_t, sysctl_crypto_t, dbusd_etc_t, gkeyringd_exec_t, gconfd_exec_t, user_home_type, xdm_var_run_t, net_conf_t, rpm_var_cache_t, file_context_t, mono_exec_t, abrt_t, httpd_modules_t, lib_t, policykit_reload_t, httpd_user_content_t, samba_var_t, afs_cache_t, abrt_helper_exec_t, httpd_user_htaccess_t, rpm_var_lib_t, net_conf_t, chrome_sandbox_t, mozilla_plugin_exec_t, ld_so_t, chfn_exec_t, cert_type, etc_runtime_t, public_content_t, nsplugin_rw_t, anon_inodefs_t, config_usr_t, sysctl_kernel_t, httpd_user_script_exec_t, pcscd_var_run_t, gkeyringd_gnome_home_t, xsession_exec_t, sysctl_fs_t, noxattrfs, noxattrfs, usbfs_t, cert_t, noxattrfs, dosfs_t, user_tmp_t, NetworkManager_var_lib_t, user_home_type, proc_net_t, net_conf_t, httpd_user_script_exec_t. 
Then execute: 
restorecon -v '/var/lib/PackageKit/desktop-files.db'

*****  Plugin catchall (17.1 confidence) suggests  ***************************

If you believe that gpk-dbus-service should be allowed read access on the desktop-files.db file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep gpk-dbus-servic /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
