Bug 325952

Selected 'system settings', 'display and monitor' then 'screen saver'.
on selecting 'screen saver' the 'system settings' closes and brings up a bug report app.
this was previously working. I have recently upgraded to Wheezy and have been checking things work.
when first installed I got desktop effects such as 'magic lamp', 'explosion', 'wobbly windows'. I was pleased as this was the first time I had got these effects to work on my radean redwood card.
I dont want to use my radeon disk as its non-free and prefer to use Debian/KDE free software.
I have been using Linux for some years now and am familiar with Debian and can use script to a point but would class myself as 25% there.
I am new to Debian KDE as I thought i was good enough to start using a more advanced system.
Previously used Debian gnome.

Reproducible: Always

Steps to Reproduce:
1. system settings
2. display and monitor
3. screen saver
Actual Results:  
bye bye

Expected Results:  
opened screen saver and allowed selection of maybe 'aquarium' i think thats the name.
