This might be a bug, and it's a problem if you have old (pre 1.7.8-jumbo8 or so) untagged entries in the pot file. Does it work in Jumbo-5? Or 1.7.8-jumbo-8? Please try both raw-md5 and dynamic_0 (and raw-md5thick if available). If not, it might have "happened" here: http://www.openwall.com/lists/john-dev/2011/10/24/10 but it was supposed to read bare (old) hashes from the pot file, but always store new ones with tags. Note that in latest git, "raw-md5" is a thick one, not a dynamic. That might be a separate version of the "same" bug (but from a quick test it seems dynamic is affected too). magnum
