<p>Should allow for an empty <code>path</code> as none, as the setting will be the empty string rather than NULL, so this will lead to try and open file <code>""</code> and lead to a warning.</p>

<p>BTW, apparently VTE's implementation of this fails silently when the file can't be open/open as an image.  Warning is better for us I suppose, though.</p>
