 affected by this issue and they have no plan to update ImageMagick. (So,
 the faster release, the better.)

 No, I do not have a target date at this point. Am concerned about the
 breakage, and it absolutely needs to be fixed (it's a bug, and the fix has
 been committed to trunk), but it's worth noting that this seems to be the
 only host that users have reported issues with thusfar. I'm very
 interested in knowing if there are more instances.

 ImageMagick 6.4.6 was released in 2008, so this is probably the reason
 that fewer users are affected than would otherwise be.

 It's likely that the timeline for 4.5.1 will be discussed at next week's
 dev meeting (April 20 at 2000 UTC).
