Equipotential bonding would solve it. I cant comment on the risk of
the situation, as I dont know if its filter capacitive leakage or
cable damage. One's harmless, one liable to be fatal.

Exactly.

We don't know what's causing the problem, but there is a chance it could be
something that could fail into becoming extremely dangerous.

Risk assessment mental exercise:

1) Dangerous condition not proven but suspected: outcome potentially
devastating

2) Inconvenience of isolating suspect circuit - sod all.

Makes it a no brainer - turn it off and check it out.

which means we know its not capacitors in the power supply, making the
likelihood of a potentially fatal fault fairly high.
