How can this issue be "Resolved" when in fact it happens (per above) in Vanilla unmodified Minecraft using a Minecraft generated world map?!

Encouraging us to report bugs and then responding unintelligently really is counter productive, Mojang.

And here is MY bug report following the steps outlined above using preset "2;0;1;decoration" (without the quotes) on a Windows 7 64-bit PC:
