Not necessarily. A bit of leakage is almost considered normal on some
electrical equipment - and it may not even BE real leakage - it could
be inductive or capacitive inductance

What types of equipment would do that?

Some equipment will have some low value capacitors going from the AC wiring
to the chassie. This creats a low value of leakage curent. If the
equipment has the proper 3 wire plug , there is no problem. Without the
ground wire, you could feel a tingle if you got between the device and
ground.
