Comment 8 for bug 1123710

Once I fix gnome-exe-thumbnailer, but not winetricks, apt has a similar problem: it gets to the winetricks recommends, determines it wants winetricks:i386, winetricks:i386 says it wants cabextract:i386, this then conflicts with cabextract:amd64. Apt then suggests removing cabextract but not actually installing winetricks due to another conflict, so the suggested removal of cabextract is unnecessary.

I'm beginning to think I need to make some automated tests for an elaborate series of multi-arch edge cases.
