Handle correctly the reject of 'install needed files'.

Original Subject: Cannot start OpenVPN, binary not found Bundle Debian

Can't start eip, using bundle Bitmask-linux64-2014-05-30-dde86d75 on Debian 7 with Gnome fallback.

I guess the most relevant piece in thte log is the failure to find openvpn: http://pastebin.com/77UE3WbV

For the sake of giving more information in my bugreport:
kwadronaut@kastanje:~$ dpkg -l openvpn
