I never changed this setting while upgrading vim:
   ~> ls -l /etc/alternatives/vim
   lrwxrwxrwx 1 root root 16 Oct 20  2013 /etc/alternatives/vim -> /usr/bin/vim.nox

and I never ever use gvim. So this really has changed in that version
and was working before.

That is no solution as it removes all local set options from the view
file.

Proper behaviour would be to ignore that setting if it is set to empty
value in view.
