View row with doc==null

[Marcello Nuccio]

Don't know how, but I have a view that returns the following row:

    {"id":"510427_2011_1","key":["510427",2011,1],"value":1,"doc":null}

i.e. it has doc==null when queried with include_docs=true. The doc
with the given _id is deleted. The database is compacted. The views
are compacted and cleaned (done via Futon). CouchDB is version 1.1.1
built with build-couchdb on Ubuntu 11.10.

Is this normal behaviour?

Thanks,
  Marcello
