Comment 24 for bug 1989163

@ahasenack: I think probably the reason you didn't see the fix work was because you installed the old, bad XScreenSaver package first, which the test case does not specify you should do. If you want to have the fix work *after* installing the bad XScreenSaver package, you need to close the screensaver config program, then open a terminal and run "killall xscreensaver; rm ~/.xscreensaver", then open the screensaver config app again. At that point the Preview button will work.

I will do a Lunar upload to bump the version number. In the mean time, can you test again with that extra info?
