Plasma Networkmanager widget cannot connect to past wifi networks

[Rohan Dhruva]

I am using Kubuntu Oneiric, updated to the latest version. I use plasma-widget-networkmanagement to connect to wifi networks. If I have already connected to a network in the past, the system is unable to connect to it again. Clicking on a 'known' network silently fails without any error, and a red cross appears on the wifi symbol in taskbar.

To resole the issue, I need to go to "Manage Connections" -> "Wireless" -> and delete the entry for the wifi network I'm trying to connect to.
