cannot login after logout from panel

[Dave Goldsbrough]

Using Startup application one was added to play a sound at login.
This was the command entered
paplay /usr/share/sounds/ubuntu/stereo/desktop-login.ogg

It works from cold boot but if you logout from the panel and log back in the system freezes and needs to be rebooted from the top panel.

Deleting the Startup application to play the sound does not alter things - so the bug may have been present before - just not noticed it.
