Forwarding this information about ZIM reader Kiwix, which is the reader commonly used for the Offline Wikipedia projects.
Many of you on these lists I know have connections to both OLPC and/or Offline Wikipedia, so I thought that you might at a minimum interested in the update and hopefully also interested in helping test!
we finally have fixed the big bug impacting loading of ZIM files with
0.8x versions of the OLPC OS. So, Kiwix should work now and be able to
load any ZIM file. No bug anymore concerning Kiwix on Sugar is still
open on our side.
