--- Comment #12 from Alex Folland lexlexlex@gmail.com --- I see that the change was committed to wine. Wine-staging has been rebased to include that, so now I don't have to apply the patch. Thanks!
My result after rebuilding wine-staging with the change is the same as my most recent result: "Path is invalid."
