Pasting a url with parameters into the RTE's view HTML source mode or by setting a link by external url via the Element Browser will cause the the RTE to report the url as invalid after saving. Removing the url parameters will not invoke the error.

<a href="http://localhost/gburg/?id=1487&card=2&title=Wisdom&quot; target="_top" title="Wisdom eCard"><img src="fileadmin/local/ecards/card2sm.jpg" style="width: 175px; height: 132px;" alt="Wisdom eCard" /></a>
</p>

url after save as displayed in the RTE view HTML Source:
<p>
<a href="http://localhost/gburg/?id=1487&card=2&title=Wisdom&quot; target="_top" title="Wisdom eCard" rteerror="No page found: 0" style="border: 2px solid red; background-color: yellow; color: black;"><img src="http://localhost/gburg/fileadmin/local/ecards/card2sm.jpg&quot; style="width: 175px; height: 132px;" alt="Wisdom eCard" /></a>
