Please let us know your configuration.  I think that it's
~/.gnupg/gpg.conf on Fedora.

Please include the version output of gpg --version in your report.

Is it complete session log of yours?  I mean, GnuPG should ask you
passphrase here.

Possible case: If you enable gpg-agent by the configuration of
use-agent, passphrase handling (and others) is done by gpg-agent.  And
when your gpg-agent doesn't work and returns "", and it is failed and
caused "bad key" error.  If so, please try with --no-use-agent.  To
investigate what's going on with gpg-agent, please also let us know
the output of:

    $ echo $GPG_AGENT_INFO

Thanks,
