Looks like this happens when an image file doesn't exist:

<figure class="mw-default-size" typeof="mw:Error mw:Image/Thumb" data-mw='{"errors":[{"key":"apierror-filedoesnotexist","message":"This image does not exist."}]}' id="mwBA"><a href="./Special:FilePath/ParthibanKanavu.jpg" id="mwBQ"><span resource="./படிமம்:ParthibanKanavu.jpg" data-width="220" id="mwBg">படிமம்:ParthibanKanavu.jpg</span></a><figcaption id="mwBw"><b id="mwCA">பார்த்திபன் கனவு</b></figcaption></figure>
