 No http errors or php errors in logs. But no thumbs are generated, only
 the original image sits in the uploads directory. It fails silently.

 Testing with the 10MB image using GD in 5.2 fails with (the dreaded) `HTTP
 Error` here. I don't currently have access to ImageMagick. Would you be
 able to "get to the bottom of it" and determine the exact ImageMagick
 error and where it comes from?

 > I'm just theorizing here that it's the new 5.3 really large original
 resize that fails...

 Yes, it's possible it fails as the size is larger than the previous
 default sizes. If it fails at this point, the retries will still try to
 create the same `-scaled` image. However there are even larger "sub-sizes"
 added by plugins, and generally wp-admin should be able to handle this
 kind of sub-sizes.

 The bug in this case is that it fails silently and the user is not
 notified to scale down the image and try to upload it again. Would be
 great to catch the error and show that error message in the UI.
