Are you sure you do not have two dhcp servers running?
Yes. This problem is accrue whit open wireless network. But recently I do not test whether it is work or not?!
Can you upgrade to a newer Plasma NM version and test again? These packages are for OpenSuse 11.4: http://lists.opensuse.org/opensuse-kde/2011-05/msg00035.html The version you are using is probably old. I cannot reproduce this problem.
