This is what I have:

,----[ C-h v debug-on-event RET ]
| Enter debugger on this event.  When Emacs
| receives the special event specified by this variable, it will try to
| break into the debugger as soon as possible instead of processing the
| event normally through `special-event-map'.
| 
| Currently, the only supported values for this
| variable are `sigusr1' and `sigusr2'.

What version of Emacs are you using?
