I also verify Amr's observation that this bug is fixed with the combination of wine1.6 from xenial-proposed and gnome-software from ppa:ubuntu-desktop/gnome-software.
I then purged that PPA and wine still showed correctly in gnome-software so maybe this was even fixed already in a previous gnome-software update.
Therefore, I am marking this fix as verified. Thanks Amr!
