Insight
Due to a bug in the keychain package the '--noask' option wasn't always used, this caused the Qt4 ssh-askpass dialogue to get loaded before a window manager was fully-started, preventing the user from entering the passphrase as the dialogue never gets focus without a window manager running. This update fixes this issue by insuring the '--noask' option is used when logging into a DE (the Qt4 ssh-askpass dialogue is only shown when the user opens a new terminal emulator window).
