Description Old Uncle 2011-12-17 08:14:11 UTC
SELinux is preventing /usr/libexec/gdm-session-worker from 'add_name' accesses on the directory .xsession-errors.XXPOI75V.

*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If you want to enable polyinstantiated directory support.
Then you must tell SELinux about this by enabling the 'allow_polyinstantiation' boolean.
Do
setsebool -P allow_polyinstantiation 1

*****  Plugin catchall (11.6 confidence) suggests  ***************************

If you believe that gdm-session-worker should be allowed add_name access on the .xsession-errors.XXPOI75V directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep gdm-session-wor /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
