Comment 2 for bug 516873

I took a look into this and it appears to be by design (from the original team I suppose). The way it is setup currently, if you are starting from a place like Favorites or System (some "item" that does not have an accosiated menu), it will use the 'fade' transition. Going from an 'item' that has a .menu file than it will use the slide.

I can make the change to fix this to be consistent if someone will let me know which way "ubuntu" would prefer it to be .. either fade or slide.
