I search for the previous thread about this and merge it.

Python widgets are known to cause trouble, recaller did for me.

Proper way to identify is to remove all 3rd party widgets, restart hildon-home and add one at a time (4 days I recommend). It is not said that the program you added last was doing wrong but might be incompatible with another widget. And for starters hildon-desktop is not hildon-home, hildon-desktop includes moving between desktops, edit-home, Operator Name, Status-Menu (+ icons) and App-Menu-Icon! Hildon-home is everything on your desktop (widgets, shortcuts, bookmarks, contacts)
