Description Karel Volný 2013-08-07 08:22:17 UTC
Description of problem:
SELinux is preventing /usr/libexec/kde4/lnusertemp from 'create' accesses on the lnk_file /var/tmp/kdecache-lightdmjEJA94.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that lnusertemp should be allowed create access on the kdecache-lightdmjEJA94 lnk_file 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 lnusertemp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
