Bug 561281

My system sometimes fail to halt. It happens in about 20-30% of cases.

How to reproduce: Start GNOME, Shutdown from the menu

Actual behavior: Session logs-out, halt does not continue

Work-around: Ctrl+Alt+F1 (really, only pressing this key combination will finish the halt)

Shutdown was called at about 08:13:10.
Ctrl+Alt+F1 was pressed at about 08:34:17.
