If you take any head and put it in water, it will break and drop a wither skull.

Can't reproduce. Is this singleplayer or multiplayer? Are you placing the head in water or making water hit an already placed head? From above or from the sides? Are you using any mods or vanilla?
I just tested it in vanilla single player and it's not a problem. It's probably just a glitch with one of the plugins on my server.

We cannot be held responsible for bugs that may be introduced by mods, and as unlikely as you'd think a lot of bugs are actually introduced by mods that people just assume are from vanilla. I can't tell you how many bug reports we've had of people who used optifine where it turns out it was a bug in that...
Tested this on Win7 and I can not duplicate this bug. Could me Mac specific though I doubt it.
