Thaumcraft crash *sigh*

I can't log in now due to this crash: http://pastebin.com/6F9xYycn

Apparently something is wrong with essentia tubes, but the only reference to this error I find is from updating to thaumcraft 4.1 and using an old thaumic tinkers, which is obviously not the case here.

I am asking around on IRC to try and figure out what is going on.

 

Ok, talking with other people in IRC that have had the issue we have narrowed the issue to essentia valve pipes, or another essentia tube on my hotbar, I believe I placed all my normal tubes so it should be the valve pipes.

 

So either A. Someone has to edit my player.dat file and remove the offending item, or if a mod times it right, they can /kill me as soon as I log on, I think I am at my base so it should be fine.

 

Logging into single player to check the IDs. Also thank you for the quick response!

and here we have the culprit: 5x 2425:1 in slot 4

 

I am doing more testing in single player to ensure it is the problem.

**edit**

Confirmed. I takes a client restart with a valve tube on the hotbar to reproduce the error, just logging out and back in will not cause it.

Ok, so I got back on the server by attempting to log in several times, the first few mashing the 5 key to get to inventory slot 4 (Minecraft wiki says that it starts at 0) then the next time doing a ctrl+q mash to drop the stack before it rendered and it worked.
