Since I last updated my system, I am not able to unlock SSH keys protected with
a passphrase that requires me to use the dead keys in my keyboard layout (en-US
international). When I press any dead key, it is just ignored, so it looks like
it's waiting for the next key press and the error can only be seen if I click
on the icon to show the password.

This can cause serious issues for users that rely on the GUI to unlock their
keys.
