I have seen this error a few times. If you map some polygons within QGIS sometimes the add ring tool does not work.
I tried a few things to fix it. Checking the geometry validity, simplifing the polygon, saving out the selection to a new shapefile. All of these failed.
One fix, was to create a brand new shapefile and copy the poly into the new shapefile. Then the add ring tool would work again.

I have the corrupt shapefile attached. If someone can look into what happened to the shapefile and find the link how it was caused by qgis that would be great.
