When you check validity of a multipolygon where its components may share a limited number of points, qgis validity checker throw an error even if it is valid for OGC.

If you want to reproduce this issue, you may union the two valid polygons attached to this bug report (shp files) and make a multipolygon which is reported as invalid by validity checker.
