UI shows "Error: notfound (Document does not exist) " for a document that was obtained from all_docs ( documents page in the UI ) if key is hashed to the wrong vbucket

I ran some tests which inserted all documents to vbucket #0 and this occured.

this happens to some of the docs. i picked doc by id : 0001261e2060303a

UI obtains couple of IDs when you enter the documents tab by running this query

http://127.0.0.1:8091/couchBase/default/_all_docs?skip=0&include_docs=true&limit=6&_=1353805358131
https://friendpaste.com/5HBhYD6xivnnOE4JMLm0St

and then when i click on edit document it runs this query to read the data :

couchbase-macbook-13:bin farshid$ curl "http://localhost:8091/couchBase/default/0001261e2060303a"

{"error":"not_found","reason":"missing"}

according to ep-engine this key exists:

couchbase-macbook-13:bin farshid$ ./cbstats localhost:11210 vkey 0001261e2060303a 0
