I'd like to believe you, and I updated from CVS a few minutes ago, but
now one (just one) of your recent messages
(<m3d70svvis.fsf@quimbies.gnus.org>) still causes the old error:

And now that I can see them, I have trouble believing that these are
the images you intended to be displayed.

Notice that, in the 2nd, the image isn't placed properly, either.
