To be exact.
<pubDate>Thu, 02 Apr 2009 13:00:45</pubDate>
by the post entries doesn't validate as it should be in format:
<pubDate>Thu, 02 Apr 2009 13:00:45 +0000</pubDate>

It is coming from line 36 of bp-activity-site-wide-feed.php
<pubDate><?php echo mysql2date('D, d M Y H:i:s +0000', bp_activity_feed_item_date(), false); ?></pubDate>
however few lines above at line 26 it delivers in correct date:
<pubDate><?php echo mysql2date('D, d M Y H:i:s +0000', bp_activity_get_last_updated(), false); ?></pubDate>
