Bugs on /feed-item/ and lose prefix of tables

Hi!

Many thanks for this perfect and necessary product. But now I have some problems.

For 5.x-1.0.

There is a mistake on page mysite.com/feed-item/1 after change of some nodefeed's parameters:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DESC LIMIT 0, 10' at line 1 query: SELECT node.nid, feedapi_node_item.nid, feedapi_node_item.timestamp AS feedapi_node_item_timestamp, created FROM rss_drupal_node node LEFT JOIN rss_drupal_feedapi_node_item feedapi_node_item ON node.nid = feedapi_node_item.nid WHERE (feedapi_node_item.feed_nid = 4) ORDER BY feedapi_node_item_timestamp DESC, DESC LIMIT 0, 10 in /var/home/......./public_http/includes/database.vbulletin.inc on line 164.

After that

During update 5.x-1.0. to 5.x-1.x-dev (2008-Feb-19):

user warning: Table 'nattabi2.feedapi_node_item' doesn't exist query: REPLACE INTO rss_drupal_feedapi_node_item_feed (feed_nid, feed_item_nid) SELECT feed_nid, nid FROM feedapi_node_item in /var/home/...../public_http/includes/database.vbulletin.inc on line 164.

...

The following queries were executed

feedapi_node module

Update #3

    * CREATE TABLE IF NOT EXISTS {feedapi_node_item_feed} ( `feed_nid` int(10) unsigned NOT NULL default '0', `feed_item_nid` int(10) unsigned NOT NULL default '0', PRIMARY KEY (`feed_nid`,`feed_item_nid`), KEY `feed_nid` (`feed_nid`), KEY `feed_item_nid` (`feed_item_nid`) ) DEFAULT CHARSET=latin1;

    * <strong>Failed<strong>: REPLACE INTO {feedapi_node_item_feed} (feed_nid, feed_item_nid) SELECT feed_nid, nid FROM feedapi_node_item

    * ALTER TABLE {feedapi_node_item} DROP `feed_nid`

....

All tables have a prefix (for example, 'rss_drupal_').

Thanks.
