The IconSmallError attribute is applied to the plug-in class. It allows the plug-in creator to specify a small icon to displayed in association with the plug-in in the UI. This icon will be displayed when the plug-in is in an error state.
This typically will occur when there is a problem loading the plug-in. This can either be an absolute path or the simple file name of the icon if the icon file is located in the images directory of the plug-in folder structure.
