Some incorrect RSS feeds may produce empty summary in RSS summary block

Dear Friends,

I am using Drupal 6.2 + PostgreSQL 8.3 + Php 5 under Linux.
Aggregation is version 6.2. Am I posting in the right place ?

I aggregate 30 rss streams.

It appears that some streams have incorrect content.
For example, time may be NULL or zero.

If such a news is included in database, it results in a blank summary (in block).
The news block is blanck, but the link and the detailed page works fine.

This seems to be a bug in the line of aggregator.module

I replaced :
$result = db_query_range('SELECT i.* FROM {aggregator_category_item} ci LEFT JOIN {aggregator_item} i ON ci.iid = i.iid WHERE ci.cid = %d ORDER BY i.timestamp DESC, i.iid DESC', $category->cid, 0, $category->block);

which may produce NULL results if for some reasons date or content is zero.

with :

$result = db_query_range('SELECT i.* FROM {aggregator_category_item} ci INNER JOIN {aggregator_item} i ON ci.iid = i.iid WHERE ci.cid = %d ORDER BY i.timestamp DESC, i.iid DESC', $category->cid, 0, $category->block);


and now news display very well.
