Bug 289977

Application: kcmshell4 ()
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.41.4-1.fc15.i686 i686
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
After I changed the time zone and clicked OK, the crash reporting assistant popped up. The time zone was successfully changed. There was also an SELinux Alert:

SELinux is preventing /usr/libexec/kde4/kcmdatetimehelper from write access on the file /.config/Trolltech.conf.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label. 
/.config/Trolltech.conf default label should be default_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /.config/Trolltech.conf

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that kcmdatetimehelper should be allowed write access on the Trolltech.conf 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 kcmdatetimehelp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
