[Kde-pim] KMail and "encrypt to self" issue

[Alexis Papadopoulos]

Hello,

I'm attaching a patch which modifies cryptplug in order to set a passphrase 
callback (see gpgme_set_passphrase_cb) for when no gpg-agent is running. The 
callback code is directly taken and adapted from libkpgp which is rather nice 
since you get the same dialog when you wish to encrypt a mail (although when 
decryption DOES work, there's yet another dialog which is used, don't know 
exactly where it comes from, probably likpgp, which isn't very consistent, 
but then again, it works...).

This fixes the following issue :
_ Any encrypted mail whose PGP content is located within an 
application/pgp-encrypted Content-Type will not get decrypted if no gpg-agent 
is running. In other words, mails in your SENT folder which were encrypted 
with your private key ("never encrypt to self" must be unchecked), or 
encrypted mails you receive from other KMail clients (at least in the tests 
I've made)

I leave this to your consideration and will open a bug entry if deemed 
necessary.

Btw, Markus, could you please try and launch gpg-agent to see if this fixes 
your issues ? We most probably have the same problem (although I cannot 
explain why you're asked for a passphrase with deleted keys :S). Basically, 
do this within a terminal : 
eval `gpg-agent --daemon`
kmail

Tell us if this allows you to decrypt the mails you didn't get a dialog for 
before.

Thanks,
acp
