It can't be binding to an interface that doesn't exist, so it sounds
as though you haven't disabled it properly. You can type
'/sbin/ifconfig' and look for inet6 entries. You shouldn't have any
if IPv6 is disabled. You can check for anything listening on IPv6
with 'netstat -l6'. Have you looked at the Debian wiki page at
'http://wiki.debian.org/DebianIPv6'? If you have followed those
directions for disabling, did you reboot afterwards?

I just looked at mine (kdm) and it only seems to be listening to IPv6,
but I am pretty sure it will also connect to IPv4. I just checked
google and there are some similar problems listed and some suggestions
on how to solve them. One suggests using module aliases to prevent
loading the IPv6 module
(http://www.linux.com/community/blogs/disable-ipv6-on-debian-lenny-quick-howto.html).

I wouldn't expect it to be different.

Done.
