it works fine for me...but it takes forever to boot and if you choose to view your pictures it takes you to your camera roll with no way to quickly get back to the camera. Not worth the download if you ask me
As mentioned, the problem is Quickgold. Delete it from your phone and Snapture will work just fine. As for a fix for Quickgold, just keep on eye on Cydia and if ones gets released, you will see it in the Changes section.
