This seems like a regression. It looks OK in the
manual as that example has not been edited recently
and so has not been recompiled recently either. In
the file for my local doc build it was last compiled
on 27 April 08, and was OK then, probably with 2.11.44.
I'm sorry, but I see the manual and this PDF (and also my results with
2.11.56) identical.
The warnings are not exactly errors. Another thread with the words
"durations needed" in which Mats explained very well some related
issues, can be of help.
