Comment 59 for bug 106060

Mepis doesn't have Molecules module installed
Ubuntu LiveCD after sudo apt-get install xscreensaver, selected Molecules and locked up, only mouse cursor worked, had to do hard reset

Now everytime I go into the xscreensaver configure it locks up because the Molecules is highlited

so I did gedit .gconf/apps/gnome-screensaver/%gconf.xml

and changed
screensavers-molecule
4. change "molecule" to one of the working screensavers, such as:
screensavers-sonar
as suggested in above post
I'll post the results, see if I can run GLSlideshow with My Pictures without lockup
