kde 3.2 Woody screensaver does not work

[Philippe Merlin]

Hello,
Recently i migrate from Kde 3.1.4 to Kde 3.2.
I configure the screensaver with the kde configuration center, and very few 
screensaver among all proposed  works and can be tested. But  the screensaver 
does not work at all.
It seems that the install of this part was not not very good , i want 
reinstall this part but i don't know the name of this part.
Sorry for my English.
