The ShouldTrace method's conditions are fixed to correctly trace the events based on the Level.

Keeping in mind the values for SourceLevel enum:
	public enum SourceLevels
	{
		Off = 0,
		Critical = 1,
		Error = 3,
		Warning = 7,
		Information = 15,
		Verbose = 31,
		[EditorBrowsable (EditorBrowsableState.Advanced)]
		ActivityTracing = 0xFF00,
		All = -1,
	}

and the values for TraceEventType: 
	public enum TraceEventType
	{
		Critical = 1,
		Error = 2,
		Warning = 4,
		Information = 8,
		Verbose = 16,
		[EditorBrowsable (EditorBrowsableState.Advanced)]
		Start = 0x100,
		[EditorBrowsable (EditorBrowsableState.Advanced)]
		Stop = 0x200,
		[EditorBrowsable (EditorBrowsableState.Advanced)]
		Suspend = 0x400,
		[EditorBrowsable (EditorBrowsableState.Advanced)]
		Resume = 0x800,
		[EditorBrowsable (EditorBrowsableState.Advanced)]
		Transfer = 0x1000,
	}

and simply computing the results of AND operations, you see that now the right Boolean value is returned. I also wrote unit tests for it but don't know how to include it here!
