Finally had a chance to talk to Andy Peatling about this at WordCamp NYC this weekend. These problems are caused by one of the way the activity streams were updated in BP. The quick fix he gave me:

In /wp-content/plugins/buddypress/bp-activity/bp-activity-template-tags.php

Line 255:

$content = apply_filters( ‘the_content’, $content );

Completely remove that line and save the file. That should fix the issue.

Worked like a charm for me.
