System.Runtime.InteropServices.SEHException

My version is 4.6.0f3, same as in 4.6.1p2.
Here is a exception I don’t know how to resolve it.
The related code is:
GUIContent(title.txt, null, null)

When I use “Managed” debug it throw exception as :
“System.Runtime.InteropServices.SEHException” exception in UnityEngineProxy.DLL
External component has thrown an exception.

Then when I use “Native” debug mode, it throw exception as:
Platform::NullReferenceException ^

System.ArgumentNullException: Value cannot be null.

at System.StubHelpers.HStringMarshaler.ConvertToNativeReference(String managed, HSTRING_HEADER* hstringHeader)

at WinRTBridge.Utils.ScriptingGUIContentToTempNativeGC(Int64 content, ScriptingGUIContentToTempNativeDelegateGC callback)

Any ideas?

Try passing empty strings instead of nulls

it solved.
Thanks.
