Cursor movement logs me out

[Timothy Murphy]

I wonder if anyone else experiences this?
Sometimes when I move the cursor with the pointer on my ThinkPad T510 
I am apparently logged out, and have to re-enter my password.

This doesn't really worry me, as the re-entry after giving my password
takes only a second, so it is not a proper logging out.

I should say I'm running Fedora 22 with KDE-4.14.11.
