Comment 3 for bug 208668

This looks like a thinkfinger bug; "Error: Bad address." is (I think) being emitted by _libthinkfinger_store_fingerprint, and indicates some kind of memory corruption within that library. Perhaps allocating a 10KB array on the stack is too much for it? It's hard to be sure from here, though.

Perhaps somebody else with a thinkfinger setup can figure out what's going on here.

Could you attach /etc/pam.d/ssh and /etc/pam.d/common-auth for good measure, please?
