The new styles for thumbnail boxes introduced in r18237 require classes which are not present in older thumbnails. Squid- or parser-cached pages containing the old renderings do not display correctly with the new style sheets: the boxes are missing borders, backgrounds, etc. New styles should generally be backwards-compatible, showing old rendered content in an acceptable manner.

Correction: change introduced in r18303
Fixed in r18461
These styles were introduced to support the ImageMap extension. The old selectors do not work with ImageMap, which inserts an extra div between the thumbinner div and the image. I'm going to remove the old selectors again, to restore correct styling for ImageMap. The HTML caches will have expired on Wikimedia by now.
Issue obsolete... fixed by time. :)
