The only new application was this one (I am pretty sure all the other ones are stable enough, since they have never reseted the desktop --except Large Statusbar Clock, as you know --.

Minutes before the reset I was trying the new animation effect in all my icons, because I had found that clicking one in the middle of a row made the one on the right disappear (does it make any sense?). After the desktop reset the animation effect started to work again and no more resets.

I will continue testing.
