           Version: 1.0
          Platform: Ubuntu Packages

KDE Platform Version: 4.10.80
Qt Version: 4.8.5
Operating System: Linux 3.8.0-19-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:

When I have /etc/cron.allow file and my username is not included it, this
dialog is displayed:

--------
The following error occurred while initializing KCron:

You have been blocked from using KCron by 
either the /etc/cron.allow  file or /etc/cron.deny file.

Check the crontab man page for further details.

KCron will now exit.

--------

Systemsettings crashes when I click on OK button.

- Custom settings of the application:

/etc/cron.allow without my username
or
/etc/cron.deny with my username

I'm using Project Neon.

The crash can be reproduced every time.

-- Backtrace:
Application: Configurações do sistema (systemsettings), signal: Segmentation
