"Undefined property" error in Related Items Extened

On some of my pages, The RIE gives an error, "Undefined property" (see e.g. ehinger.nu/undervisning/index.php/starta...ra-stilla-havet.html under "Läs också..." and "Också intressant"). It seems the error appears when the first link in the linked related article is to a Youtube video, or when there aren't enough related articles to link to.

What might be the cause of this error?

Unfortunately, this is not a problem of displaying an "empty image", but an error message.

I think the problem lies in the related article "Förhistorisk 'valkyrkogård' funnen" (ehinger.nu/undervisning/index.php/starta...yrkogard-funnen.html). The first (only) image in this article is a popup (made in JCE), and surrounded by href anchors. See code example in the attached file.

The Youtube videos were added with the standard Youtube method, with an iframe. Since RIE doesn't extract images automatically from Youtube (this is on my wish list!) I added the images manually to the articles.

Yes, but don't you think this is a bug that needs to be corrected? Instead of displaying an error message when an image is surrounded by href tags, it would be much nicer if the image itself was shown.

On my site, nearly all of my images are popups. To fix my problem, I have to put another copy of the image first in the article, but with width=0, so it doesn't show twice.

Also, many of the images are embedded from around the 'net, and not located on my server. So, to further extend my wish list for RIE, I would like embedded images to be shown by RIE, too.
