Mac RedPower related crash with Transmitters

Hello,

I am playing FTB on the MindCrack Pack v7 on a Mac with OS X 10.8 and recently can't access my world anymore. The game crashes when the world is loaded. When I can load my world, switch to a different application, then Minecraft goes into pause mode (which is fine!), but once I click on Back to Game, it says "shutting down internal server".

The last thing I did: I was in C+ mode which NEI and I middle-clicked one of RedPower's Wireless Transmitters that I had on the ground.

When I start the game and it immediately goes to pause, I can see the transmitter in the second hotbar slot. It's selected! I tried to use Inside Job to change the item ID from 12xx to 2, but no luck. I log in, the transmitter is back. (I saved of course)

I'm pretty sure it's RedPower causing this problem, but not sure where to report this. I would be fine if my inventory was gone, but I don't know how to wipe it.

EDIT: I just saw there are some more folks having this problem.

Thanks,
