renewing of expired signatures

[Philipp Gühring]

Hi,

GnuPG has problems renewing expired signatures on keys, when the old signature 
(that already expired) is still on the key. The old expired signature is 
still on the key, and a new signature isn´t done when trying to renew it.
The workaround is to manually remove the old signature before creating a new 
signature.

Is this a bug or an intended feature?

Best regards,
Philipp Gühring
