What's strange about that? "time.sleep(10)" doesn't mean "immediately
print out debug information". It means "do not do anything at all in
this program for around 10 seconds".

All it does is print the debug information for the Deferred you got the
_debugInfo attribute from. It doesn't understand your code or know
where the source of your error is. It's just a function that gives you
the stack traces associated with a particular Deferred.
If you want a different stack trace, call the method on a _debugInfo
from a different Deferred object.
