EDIT: it seems it does work, but the password are always asked anyway. I have to close anytime the window that asks the password.
I installed Gnome Keyring some month ago for git, and it worked well. Now it does not work anymore. It asks me for the key to unlock it, but the stored passwords (printers, internet key...) are not used, I have to type them every time.
I'm using it on Lubuntu 14.04
