Comment 28 for bug 1085511

I had the same problem. I fixed it running the following commands:

$ sudo apt-get purge netflix-desktop
$ sudo apt-get purge wine
$ sudo apt-get autoremove
$ sudo rm -Rf ~/.wine-browser
$ sudo rm -Rf ~/.netflix-desktop

$ wget http://downloads.sourceforge.net/wine/wine_gecko-2.24-x86.msi
$ sudo mkdir -p /usr/share/wine/gecko
$ sudo mv wine_gecko-2.24-x86.msi /usr/share/wine/gecko/

$ sudo apt-get install netflix-desktop
$ sudo rm -Rf ~/.wine-browser
$ sudo rm -Rf ~/.netflix-desktop

I'm running Ubuntu 12.04
