[Bug 446303] Re: [Karmic] [Jaunty] kubuntu network manager can't connect to network with WEP encryption

[smidl]

I can confirm that this bug still exists with 
plasma-widget-networkmanagement_0.9~svn1029786-0ubuntu1_amd64.deb

nm-applet works without any problems. The difference is in the way they
launch dhclient. I remember having similar problems in debian, where the
issue was related to calling dhclient for ipv6 interface rather than
ipv4.

Relevant parts of daemon.log for plasma -network-manager:
