The latest updates contain gstreamer 1.5.2, which appears to be badly broken. gst_init() causes an assertion failure inside gstreamer (at least on the desktop), meaning that *no* thumbnailing of any video or audio file is possible. (It also means that we can no longer land any fixes to the thumbnailer in Jenkins, because our tests (correctly) fail.
If the above problem was caused with an image that still uses 1.4.5, then it's almost certainly also a gstreamer problem. It hangs, produces black thumbnails, or errors out at random.
There isn't a lot the thumbnailer can do about this :-(
@alecu: almost certainly not.
