Stop Totem Saving Your History

To permanently remove the recent file list from totem, edit /usr/share/totem/totem.ui as root and change the following line: (Change square brackets with angle brackets.)

[separator name="recent-separator"/]
[placeholder name="recent-placeholder"/] 

to:

[!--[separator name="recent-separator"/]
[placeholder name="recent-placeholder"/]--] 

N.B. Remove the part that you added to reactive history.
