When trying to get the path to a platform's device image file using IPlatform.DeviceImagePath, this exception occurs:

System.ArgumentNullException: Value cannot be null. (Parameter 'paths')
   at System.IO.Path.Combine(String[] paths)
   at Unbroken.LaunchBox.Windows.Data.Platform.GetCustomThemeImagePath(String imageType)
