 My Video Quicktags plugin has had on and off reports about it breaking the
 sending of pingbacks.

 A user of the plugin has reported to me that the issue is due to an
 apostrophe in an HTML comment inserted into the `<head>` by my plugin:
 http://plugins.trac.wordpress.org/changeset/128694

 > we analysed the Ping Bug of your Plugin. XMLRPC wants to check the page
 that is pinging and returns the Error 17: "The source URL does not contain
 a link to the target URL, and so cannot be used as a source."[[BR]]
 > [[BR]]
 > The Problem is the "'" in <!-- Viper's Video Quicktags line 2651 of
 Version 6.2.5[[BR]]
 > [[BR]]
 > When XMLRPC executes "$linea = strip_tags( $linea, '<a>' );" and your
 Plugin is running only other stuff will show. Not right the Content.

 Assuming this was indeed the cause, shouldn't WordPress be smarter than
 that?
