Well, what do you know, I'm getting the same message when I run
dailypic. It appears not to be the image-magick that is in difficulties
but the enscript which does not recognise the @ as a special escape. 
This worked on Friday, and not since. Something has changed, but
nothing that appears to affect enscript.

I'm a bit lost. It took me ages to understand how to work the escapes
stuff in enscript to get the coloured output into the picture, and
really I don't know how to fix this.
