I should perhaps add some more information, this is a new 
installation running WP 2.6.3, I've turned off all plugins 
except the one I'm trying to debug, I'm using the default theme.

The plugin code looks like this:

function jimagelinker( $content )
{
     return "<div><a href=\"xx\"> <img src=\"yy\" />  </a> 
<p>text</p> </div>";
}

add_filter ('the_content','jimagelinker',9);


Can anyone give a hint on why this is happening?
