Comment (by vanyukov):

 Replying to [comment:19 azaozz]:
 > Looking at 48522.diff again, it changes the behaviour in
 `_wp_make_subsizes()`. Until now errors while creating a particular sub-
 size were silently ignored. As the sub-sizes are created in a loop, that
 allowed the loop to continue and (attempt to) create the next sub-size.

 Yes, I did see that part. That's why I said it was not a patch. I believe
 you were planning, at some point, on having WordPress auto regenerate
 attachment sizes during a theme switch, for example? There would have to
 be a way to continue on if one of the attachment sizes is not generated
 for some reason.

 Regarding 48522.diff. Won't that seriously limit the capabilities of hosts
 that are not able to accommodate the heavy lifting of ImageMagick? With
 the patch, I'm getting no images at all and am required to downsize the
 original. What if that's not an option? I can see so many scenarios that
 would make me want to upload attachments as large as possible. I'm fine
 with a host not being able to generate the largest attachment sizes.
 That's my concern. But I don't want WordPress to make that decision for
 me.
