I can confirm that if I copy /var/cache/man/index.db from a 64-bit
machine to a 32-bit Lucid machine, I get the same error:

  $ uname -m
  i686
  $ lsb_release -r
  Release: 10.04
  $ accessdb mandb_index.db_x86_64
  gdbm fatal: read error

That same operation on a Precise 32-bit machine fails with a slightly
different error message:

  $ uname -m
  i686
  $ lsb_release -r
  Release: 12.04
  $ accessdb mandb_index.db_x86_64
  accessdb: can't open mandb_index.db_x86_64 for reading

Opening this _x86_64 file on a 64-bit Lucid machine works fine.... but
on that machine the _i686 file fails:

  $ uname -m
  x86_64
  $ lsb_release -r
  Release: 10.04
  $ accessdb mandb_index.db_i686 | less
  accessdb: can't open mandb_index.db_i686 for reading: Invalid argument
