Xubuntu's default session is "Run XClient script" which fails to load any screensavers. Might be a problem with the XClient script? Choose "Xfce session" in gdm and the screensaver, xflock4 will work fine.
What extra things that the XClient script actually does and where is it located?
I confirm that.
