Comment 8 for bug 897411

@Paul Wise (Debian) (pabs):

Please don't tag it as "Fix Released".
I still have crash message when I try to start it as user. There SHOULD BE a message "This program requires root privileges to work" or something like that. Instead, I have:
$ iotop
Traceback (most recent call last):

    raise err
OSError: Netlink error: Operation not permitted (1)

Is that correct behaviour, in your opinion?

Checked with iotop, version 0.4.3-1ubuntu1, architecture i386.
