I am also experiencing this problem with lightdm 1.4 and lightdm-kde on Arch Linux. Steps to reproduce:
1. Login as User1. 2. Start a new session as User2. 3. Switch back to User1. 4. Log out as User1.
5. Screen sits with blinking cursor. I can manually switch to User2 using FN + F8, or what-have-you.
Once I log out both users lightdm returns to the login screen as expected. I am able to reproduce this bug every time.
