passwordless pgp signing with evolution

[ahbart]

I use GNUPG to sign my outgoing messages from evolution.
If I use claws for another mailaccount, Claws never asks me for my pgp key password, but evolution does not want to remember this password. With every Evolution session it asks me for the gpg password once. Why is this password not stored in the key application (seahorse) which is opened during login to linux?
Is there a reason for this? Or is there a solution possible?

Nobody? Is there no solution or does nobody use pgp signing of e-mail (in Evolution)?

I am looking for a solution to this problem these days, too. Otherwise I would report it as a bug. Already tried "/usr/bin/gpg-agent --daemon".
