Dear fellow Selinux experts,
Now setroubleshoot(er) is working fine and I see a great flood of avc's, some are repeating offenders :( ***.kde*** one especially :(
Summary:
SELinux prevented kde4-config from writing .kde.
Detailed Description:
SELinux prevented kde4-config from writing .kde. If .kde is a core file, you may
want to allow this. If .kde is not a core file, this could signal a intrusion
attempt.
Allowing Access:
Changing the "allow_daemons_dump_core" boolean to true will allow this access:
"setsebool -P allow_daemons_dump_core=1."
Fix Command:
setsebool -P allow_daemons_dump_core=1

Summary:
SELinux is preventing the gdm-session-wor from using potentially mislabeled
files (.xsession-errors).
Detailed Description:
SELinux has denied gdm-session-wor access to potentially mislabeled file(s)
(.xsession-errors). This means that SELinux will not allow gdm-session-wor to
use these files. It is common for users to edit files in their home directory or
tmp directories and then move (mv) them to system directories. The problem is
that the files end up with the wrong file context which confined applications
are not allowed to access.
Allowing Access:
If you want gdm-session-wor to access this files, you need to relabel them using
restorecon -v '.xsession-errors'. You might want to relabel the entire directory
using restorecon -R -v ''.

Summary:
SELinux is preventing 0logwatch (logwatch_t) "read" to /root (user_home_dir_t).
Detailed Description:
SELinux denied access requested by 0logwatch. /root may be a mislabeled. /root
default SELinux type is admin_home_t, but its current type is user_home_dir_t.
Changing this file back to the default type, may fix your problem.
File contexts can be assigned to a file in the following ways.
* Files created in a directory receive the file context of the parent
directory by default.
* The SELinux policy might override the default label inherited from the
parent directory by specifying a process running in context A which creates
a file in a directory labeled B will instead create the file with label C.
An example of this would be the dhcp client running with the dhclient_t type
and creates a file in the directory /etc. This file would normally receive
the etc_t type due to parental inheritance but instead the file is labeled
with the net_conf_t type because the SELinux policy specifies this.
* Users can change the file context on a file using tools such as chcon, or
restorecon.
This file could have been mislabeled either by user error, or if an normally
confined application was run under the wrong domain.
However, this might also indicate a bug in SELinux because the file should not
have been labeled with this type.
If you believe this is a bug, please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
Allowing Access:
You can restore the default system context to this file by executing the
restorecon command. restorecon '/root', if this file is a directory, you can
recursively restore using restorecon -R '/root'.
Fix Command:
restorecon '/root'

I will be patient here, but the .kde one, I don't understand what is wrong, is it with KDe or with selinux. I keep seeing it over and over. It goes away and then it comes back :(
Thanks,
Antonio
