Ahh, I see that was in the original mail. I didn't realize what it was at first.

What command are you using to make SVG thumbs? What distro, convert
package version, and convert version do you have? Are you using
imagemagick's convert or rsvg or something else?
I'm not sure exactly what rsvg version the WMF cluster is using but
you may want to try something from
You say "seems to be configured correctly"... what exactly are your

Those JS URLs are a local hack at individual wikis and not part of a
default mediawiki install (i think! at least last I checked) so I'm
not surprised they don't work out of the box.
