Ditto the above-it is possible the leakage is in a place where it won't hurt you, but why take a chance when the consequences are so grave? You don't mention what if anything else is on that circuit. GFCIs are designed to protect a single load. Putting several items on one circuit (lights, receptacles, etc.) increases the chance of a leak to ground. One common problem is that the white neutral wire is connected as a case ground somewhere. AND be sure that there is no tripping device (overload or reset button, circuit breaker ,etc.) wired downstream of the GFCI.
