i3lock fails to authentificate and unlock screen sometimes

Description: Ubuntu Saucy Salamander (development branch)

Sometimes i can't get my screen unlocked back and i had to switch to the text console by Ctrl-Alt-F2, log in there and kill the locker. There are auth error messages in /var/log/auth.log appear on unlock attempt:

Sep 6 09:19:34 zimbabve unix_chkpwd[28581]: password check failed for user (mike)
Sep 6 09:19:34 zimbabve i3lock: pam_unix(i3lock:auth): authentication failure; logname= uid=1000 euid=1000 tty= ruser= rhost= user=mike

Googling discovers only the fact that this behavior is common for some other lockers like Xlock and so on.

Maybe systemd-logind related bug

Status changed to 'Confirmed' because the bug affects multiple users.
