NullPointerException on server load

[zaciam]

What I did:

I have a server running the mod pack SevTech: Ages and a SevTech: Ages client.

What happened:

I connected the AutoCrafter from this modpack to an Item Extraction Cable. A little later the server crashed and is now in an endless restart loop with a NullPointerException:

What should have happened:

The server should somehow not crash that hard.
