Description

if i digitise a new multipolygonfeature in a MSSQL-Multipolygonlayer (with avoid intersections of new features) and force intersections while digitising,
the geometrytype of the new polygon is "Polygon" and not as expected "Multipolygon".

from this moment all other new added "Multipolygons" are "Polygons"

the problem occurs with the mssql provider and qgis 2.2 and 2.4
there are no problems under postgres provider.(oracle provider not tested)

snapping options and multipolygontable connection are in the screenshot

can anybody reproduce this problem?
