geometry collapsing due to intersection avoidance when filling polygons

Edit a polygon layer with island rings. Set snapping such that digitising a new polygon around the ring fills the ring and snaps to it exactly. This works a few times and then gives the error 'geometry collapsing due to intersection avoidance'. After saving and restarting QGIS, doing the same operation on the same ring with the same settings is successful. So QGIS is incorrectly raising that error. Occurs on Windows and Linux.
