Bug 490532

INFORMATION:
The screen locker shows the "Unlock failed" error message if I click on the Sleep or the Hibernate button, i.e., when I wasn't trying to unlock the screen, so the password field is clear. It does not happen when I click Switch User. Kscreenlocker is trying to unlock it without needing to.
Hibernate and Switch User work, but Sleep no longer does. I can still suspend to RAM from Plasma, from the Application Launcher for instance, or with systemctl suspend. When I click Sleep, it shows the usual, nonsensical "Unlock failed" message, interface components get greyed out, and then nothing happens. The system does not suspend. I inspected the journal, but found nothing of interest there, only a pam auth message saying that authentication failed (of course, since no password was supplied and I was just trying to suspend the PC).

EXPECTATIONS:
- No unlock attempt or fail message when I'm not trying to unlock the screen;
- Ability to suspend to RAM from the screen locker (very convenient, no need to switch user).

VERSIONS:
