Password is needlessly asked on wireless reconnect

First, I tried to use ubuntu-bug -w and clicked on the window (see attachment) to report this bug, but it complained about non-official packages, hence my manual report. So please let me know if there is not enough information.

The actual report: When I use a wireless connection, it sometimes (needs to) reconnect. When this happens a windows is displayed (I suppose to ask for my credentials), see attachment. I have stored my credentials and turning the wireless off and on, works to reconnect, so they are correctly stored as well. This is my first problem.

The second problem is with the window itself, as it is obviously of no use. Clicking OK just reopens it, pressing cancel disconnects the connection and enabling/disabling 'Show password' does nothing.
