*** This bug is a security vulnerability ***

You have been subscribed to a public security bug by Marc Deslauriers 
(mdeslaur):

After block the screen with (Ctrl+Alt+L) it shows the login interface,
my keyboard sometime start to send a keypress event with the value 5,
like the user was typing infinite times the number 5, after a while the
login interface freeze, and it is necessary to kill the X or restart the
computer.

I think that the password box crash with a big number of characters and
freeze the login interface.
