ppp requires ipv6?

["dE ." <de techno gmail com>]

Hello everyone!

I recently updated by system to get NetworkManager 0.9.6.0; but there 
appears to be a new problem/requirement in this version.

I've compiled ppp without ip6 support, and NM insists to have it, even 
when I've disabled ip6 --

Oct 16 07:42:02 OLD_BROKEN_LAP NetworkManager[4567]: <info> starting PPP 
connection

device state change: ip-config -> failed (reason 'ppp-failed') [70 120 14]

Is this intended or a bug?
