Hi Juca,
I am sending a svn patch file and a tar.bz2 containing images that I created for the editor's math menu.
Did you send the patches as attachments? It may be that mailman has stripped them out (although I normally read this list using the web archive interface, so it may be that what I see differs from what other see). Maybe put them on the web somewhere and mail through the link / links instead?
All the best, Nick.
