I can't even figure out what these folders are called. The things inside them are apparently called "keys".

How do I add another folder so that I can handle another file type that isn't listed?

You'll need to use gconftool-2 in order to do this properly:

gconftool-2 --type=bool --set "/desktop/gnome/thumbnailers/application@x-custom/enable"  "false"

And to remove it:

gconftool-2 --unset --recursive-unset "/desktop/gnome/thumbnailers/application@x-custom"

Good! Then I can use the graphical editor to add or modify keys, etc. – endolith Apr 4 '10 at 15:43
this sets a key but not creates a folder. ubuntu 11.04 – Sergey Jun 29 '11 at 9:30
