[1.7.10] [CC 1.73] [SMP] Pocket Computer(s) Cause Client Crash/Disconnect

VERSION:
CC 1.73

DESCRIPTION:
Trying to launch any form of Pocket Computer causes me to disconnect from my server.

EXPECTED RESULT:
A portable version of a ComputerCraft Computer opening up before me.

REPRODUCTION STEPS:
1. Craft a Pocket Computer, Wireless Pocket Computer, Advanced Pocket Computer or Advanced Wireless Pocket Computer (I encountered the bug with all of them, although I'd originally hoped that the advanced versions wouldn't have been bugged)
2. Right click with it in your hand.

SCREENSHOT/VIDEO:
A screenshot would not help much in this scenario, and I'm afraid I am not well-versed in recording video on Debian. I have yet to setup anything like that.

Here's a screenshot showing I made all types of Pocket Computer to test this, though: https://dl.dropboxusercontent.com/u/4202804/screenshots/2015-04-05-023531_677x217_scrot.png

Pocket computers are working for me under 1.73 in SMP.

The error message in your screenshot strongly suggests the problem is related to bukkit.

I can confirm this bug, it only happens on Cauldron. Additionally, they work fine if your cursor isn't on a block (if that makes sense).

Since it only happens with Cauldron or other similar Bukkit installations, I'm going to close this, as we don't support Bukkit.
If you are having issues without those, feel free to create a new topic for it.
