There are other things under the hood. Things that a desktop OS can't do anymore, not today. Your password manager kWallet is, once unlocked at system start, an unencrypted file where any application can access any password. If kMail fetches a signed mail in background, you'll be unexpectedly prompted to accept the certificate with no indication where the pop-up came from. Password dialogues have no priority whatsoever. When a password dialogue pops up just before another application starts, you're likely to enter your password into the wrong dialogue.
