_sum function in Erlang reduce doesn't work

Hi,

I have a view in Erlang. Its reduce() function looks like following:

        fun(Keys, Values, ReReduce) -> _sum(Values) end.

>From #couchdb irc I understood that it should work (similarly to JS view).
But Couch produces crash report when such view is triggered. Crash report is
behind the following link:

No, you misunderstood.

The exact text of the reduce in the design doc should just be "_sum". That
is not a function call but a special sentinel that couch recognizes as
signalling a summation reduction.

If that doesn't work please file a bug report on JIRA.
