WP Widget Cache sometimes inserts a <li> in the code.

I doesn’t happen every time, but every so the look of the page will get messed up a bit. I tracked it down to an extra ”

• ” inserted in the code.

For example, I see this in the source:

<!--WP Widget Cache 0.25.2 (http://www.mashget.com) Begin -->
	<li>
			<div class="execphpwidget">

Does anyone have any idea where that “

• ” might be coming from?

  I guess it has to be WP Widget Cache or PHP Code Widget but I’m not sure which one is doing it.
