Hello,

Thank you for your report.

Please use --quick-add-key instead, while I'm fixing the bug.

My changes of following commits were not enough.

	2b50f942672d9a2c325a818f21f69d3ee69255d3
	36355394d865f5760075e62267d70f7a7d5dd671

I think that something like this will be needed to apply.

Please note that 448 keys are not yet standardized as OpenPGP.  So,
format for key, signature, encrypted data may be changed in future.
