Title: Pipes with GUIs sometimes crash client

Version: 3.0.3/3.0.4

OS: Windows 7 64 bit Ultimate

Java Version: JRE 7 64 bit

Description of Problem:

I have a storage room that had a lot of distribution pipes in it. These almost always caused a crash for the client. This occurred with myself and any other people who tried right-clicking them.

Error Messages:

I have been avoiding these pipes altogether and haven't had a crash for a few days and I've only just made an account to report a couple of other bugs so I don't have a report.

Error Log:

Same as above.
