The Science Laboratory (file name "scienceModule") part spams the error log with "exception: NullReferenceException: Object reference not set to an instance of an object", which shows up in KSP.log as:

[EXC 23:30:46.400] NullReferenceException: Object reference not set to an instance of an object
	FNPlugin.Refinery.InterstellarRefineryController.Update () (at <d375857bd79f4f6682e51f45757982d6>:0)
	UnityEngine.DebugLogHandler:LogException(Exception, Object)
	ModuleManager.UnityLogHandle.InterceptLogHandler:LogException(Exception, Object)
	UnityEngine.Debug:CallOverridenDebugHandler(Exception, Object)

Commenting out the refinery module from part.cfg (line 99-103) makes the errors go away.

//	MODULE
//	{
//		name = NuclearRefineryController
//		refineryType = 0
//	}

Steps to reproduce:

1. Make a craft with the "Science Laboratory" part
2. Launch
3. Open the Console (Alt-F12)
4. The console will be filled with red error messages, once per tick or so, and KSP.log will have them as well.
