Output when trying to run either osu or path of exile

I tested new git commits and found out that wine had some problems running
games that worked perfectly before. Mostly, osu! and Path of Exile. Both games
rely on dotnet20, which I tried to reinstall using a clear .wine and winetricks
(winetricks dotnet20). The installation gave some problems (some CRT error
message) and here (attached) is the output when trying to run osu! and path of
exile.

I did some regression testing and found this commit, I think it should be
tested.
