Happens all the time around here... friend of mine got zapped not knowing that. In theory, fused neutrals are supposed to be removed whenever the wiring is worked on, but that virtually never happened unless the fuses were replaced altogether. It gets even worse when the hot and neutral fuses for one circuit aren't next to each other physically... I once had four fuses for two circuits, arranged L-L-N-N. One circuit was the center pair, the other the outer pair. Noticed that when I took a light switch apart and made one last check on the crumbly cloth wires.
