Comment 2 for bug 514775

I used synaptic to get rid of three of the knetworkmanager packages. I manually set WiCd to control Wlan0 in the preferences and it started working again.

I use now WiCd instead of Knetworkmanager, I like it that way, but I would think that a small patch could help. I consider using WiCd as a workaround.

I hope this helps others, that have the same problem.
