Basically, evolution asks you for passwords if you start it from your e-mail key, but if you start it from the applications menu or a panel it you just have to type the password for gnome-keyring-daemon. This is obviously a regression, as previous versions of evolution remembered your passwords now matter how you started it.

Steps to reproduce:
1. Start Evolution from the applications menu, create an e-mail account and check "remember password".
Check your mail (so that you have to type the pw it's supposed to remember). Close Evolution.
2. Add your e-mail key in System->Settings->Keyboard shortcuts
3. Make sure Evolution is set as your preferred e-mail app.
4. Start Evolution by pressing your keyboard's e-mail button. Notice that it asks for your password, it will do this for _every_ account, every time you check your mail, even though you check "remember password" it will not be remembered.
5. Close Evolution, and start it agian, this time from applications menu (again). The password is remembered. Note: if it's the first time you start Evolution since your login, gnome-keyring-daemon wants your password, but this is only once per login. This is how the password management is supposed to work AFAIK.

This was tested with evolution 2.8.1-1 and gnome-keyring 0.6.0-1
