Xietor, I can agree with that. However, it doesn't make sense that ethereal beings can be turned to stone.

Ghosts have no substance to turn to stone.

It seems turning to stone should work on some undead such as ghouls and vampires and other undead have an immunity for turning to stone, unfortunately since there's a mix the developers would need to create a new type of undead tag for a permanent fix. It's very unlikely JK or KO will examine all undead and provide some with a new extra undead tag.

This is one of those scenarios like the spell 'maggots' which targets the undead... this should only work on some undead and not work on ghosts or spirits.
