Direwolf20 1.6.4 1.0.12 Crash with Auto enchanter and pipes

[Bladezz]

Start with a auto enchanter, place it down and select to auto drain, select any side of the auto enchanting table in the (auto drain options) so it shows red. Place a Buildcraft pipe on the same side you had set to red on the auto drain options. It will crash then when you try to re-log onto the world you will crash again and again the only way to fix it would be to remove Buildcraft or the Openblocks from the game and start the world backup.

here is the crash report: http://pastebin.com/4rcExgLZ

Try grabbing the version from the monster modpack which is 1.2.3. Also grab the openblocks lib file as it is required from version 1.2.3.
