Steve, correct.
I just improved the error handling for these cases, to ensure the caller (ns_server) always gets a reply (instead of hanging) and a more helpful error/message like for e.g.:

{db_open_error,
    <<"default/0">>,
    {not_found,no_db_file},
    <<"Couldn't open database `default/0`, reason: {not_found,no_db_file}">>},

The gerrit change: http://review.couchbase.org/#change,12600

That seems to be caused by another error that precedes it.
This other error was corrected in the following commit:
