--- Comment #7 from real name b.wine.6883@indigo.re --- It may work on your machine, that doesn't mean there's no bug. It doesn't work on mine, that surely means there's a bug. So it's definitely *NOT* invalid.
I've just retested in a clean WINEPREFIX, without dotnet40, and it **CRASHES**, and yes, it is a valid problem.
