Fails completely if there's labeled addresses present

Thank you for your bug report. Do you still have this issue with the latest release of Ubuntu ?

  Yes. This is from a freshgutsy, i386:

Ok thank you, I reported this upstream.

It should be fixed at version 4.52 in Hardy...

It should be fixed at version 4.53 in Hardy...

This is still an issue in 4.60 with hardy. :-( Off to chat with upstream.

I've looked into this issue: http://seclists.org/nmap-dev/2008/q2/0178.html

If I'm wrong about anything, email nmap-dev or me personally at [my last name]@gmail.com

I'll leave the bug open here for the time being. This is either a bug in the documenation, or the implementation of iproute.

See https://bugs.launchpad.net/ubuntu/+source/iproute/+bug/225997

Can this still be reproduced in the currently supported releases?

Marking Incomplete until someone re-confirms, as I believe this bug is now fixed.

It's still a problem, yes. It's super-easy to reproduce, too:

Thank you for reporting this bug.

Does this issue occur in Maverick?
