Views issues: Some fields do not hide, others do not work

This also is an issue for version 6.15. See #963198: Thumbnails broken on CCK nodes. Firefox doesn't show this error, but IE, Safari and Chrome.

edit:

When the Thumbnail belongs to the correct kaltura content type and its shown, the path is: http://cdnbakmi.kaltura.com/p/376531/sp/37653100/thumbnail/entry_id/1_0r...
without belonging:
mysite.com/width/115/height/115

Ok, here's the solution:
change in node_kaltura_entry.module 682 to 685:

if ($node->link_thumb || $teaser)
    return '<div class="kaltura_thumb"><a href="'. url('node/'. $node->nid) .'"><img src="'. $node->kaltura_thumbnail_url . $size_str .'" '. $extra .' /></a></div>';
  else
    return '<div class="kaltura_thumb"><img src="'. $node->kaltura_thumbnail_url . $size_str .'" '. $extra .' /></div>';

to:

if ($node->link_thumb || $teaser) {
    if (!empty($node->kaltura_thumbnail_url)) {
      return '<div class="kaltura_thumb"><a href="'. url('node/'. $node->nid) .'"><img src="'. $node->kaltura_thumbnail_url . $size_str .'" '. $extra .' /></a></div>';
    }
  }
  else {
    if (!empty($node->kaltura_thumbnail_url)) {
      return '<div class="kaltura_thumb"><img src="'. $node->kaltura_thumbnail_url . $size_str .'" '. $extra .' /></div>';
    }
  }

This solves the thumbnail problem. We should also apply this in kaltura_media_remix.
