[TYPO3-english] Problem with t3skin after upgrade to 4.4.x

[Edgars]

 Hi, list!
  By mistake - I posted this in dev list yesterday. So, I have some
 strange problem with a few of my TYPO3 installations. Some of them
 don't load the new look (new icons, removed inline CSS) properly.
 This occurs only for upgraded sites from 4.3.x (different versions)
 on same host - purchased webspace and on localhost, all fresh
 installs looks as expected with the sprites - so this shouldn't be a
 case with an inappropriate server configuration.
  * Also, I've already deleted the cache in ../typo3conf/ and
 /typo3temp/, but nothing changed;
 * There is no skin-related extensions (only - realurl, chgallery,
 rtg_files, perfectlightbox);
  Here's the screenshot for a better picture of what actualy happens:

  Thanks for any hints!
