Description
There is layer with valid geometries. When I try to convert single features of this layer to multifeatures with "Singleparts to multipart" tool of fTools, I get non valid multipolygon. Is it possible to get non valid multipolygon from valid polygons? In such case I guess that QGIS should inform the users about this.

This has been (partially) addressed in 8710328b (SVN r14745). I am unsure whether valid single part polygons should be able to be joined to create an invalid multi part polygon. I have been unable to determine from an extensive web search, whether this should be allowed or not? Any thoughts? In any case, a warning is now issued if the output layer contains invalid multi part geometries.
