Forum:Image thumbnail rendering

I'm a big fan of scalable vector graphics and have been creating literally hundreds of such images for all kinds of wikis. However, recently I've noticed thumbnails of media files, especially but not exclusively SVGs, are not being generated/shown at least in two different wikias that I'm contributing. Examples:,. They started dying out after the last maintenance a couple of days ago. It did happen before (say, with that won't display at 34px), but wasn't that nasty, now it involves a good half of all the media files on ru.salve. I submitted a bug report asking for staff attention, but it got marked as resolved without any real progress (actually, even more thumbnails became missing since then). Can anyone enlighten us of the current state of this issue? Thanks in advance. --Radaghast 00:15, June 10, 2010 (UTC)
