My first guess would be something like a broken neutral wire, making the neutral voltage depend on the imbalance of the load between the AC phases. From the little I understand about it, you could have up to the phase to phase voltage between the broken neutral and one of the phases, with the voltage dynamically changing as devices are turned on or off. It's very confusing (since everything expects the neutral to be referenced to the earth, which is constant 0V by definition), and can burn up devices.

You're understanding is correct, if neutral is allowed to float it's voltage will depend on ratio of the load on the 2 phases. It also creates a variety of hazardous conditions and opportunities to make spicy metal.
