Why does Vim ignore my modeline values?

Question

I\'m using a Python file with the following modeline at the end:

# vim: sts=4:ts=4:sw=4

If I start Vim with this file the modeline is ignor

Answer 1

The first step is always look in

/usr/share/vim/vim74/debian.vim

and comment out the nomodeline line.

Kubuntu distributions consider it a security threat.
(EG: libcal allows you to run an arbitrary program)

This is only an issue if someone off system can run vim via a webpage. (don't trust user input.)

It is also possible to do a ddos attack using spell checker. (don't trust user input.)
