Review request for KDE Edu and Jeremy Whiting.


Repository: khangman


Description
-------

If the theme files are not found, the app crashes. To fix that, the show() method has been changed. It checks if the theme files exist. If none is found, a QMessageBox is displayed and the app closes. Else the theme is loaded by calling the appropriate slot.
