    * Secret keys are now stored and exported in a new format which
      uses SHA-1 for integrity checks.  This format renders the
      Rosa/Klima attack useless.  Other OpenPGP implementations might
      not yet support this, so the option --simple-sk-checksum creates
      the old vulnerable format.

Basically, you need to --edit your key on 1.0.7 with
--simple-sk-checksum set.  Change the passphrase (you can even change
it back to itself if you like).  Then export.
