-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

since the PGP user id depends on the identity encryptToSelf didn't work 
anymore because the message was encrypted to the no longer existant 
global PGP user id instead of being encrypted to the identity dependant 
PGP user id.
The attached patch fixes this problem. To solve this problem I had to 
add a parameter (the PGP user id which should be used) to 
Kpgp::encryptFor(...) and Kpgp::sign(...). Therefore all programs which 
depend on libkdenetwork and call Kpgp::encryptFor(...) and 
Kpgp::sign(...) will have to be adapted. My patch also includes the 
necessary patch for KMail. I guess KNode will have to be patched in a 
similar way if it also uses identities. But as I don't know KNode I 
will leave this to the maintainers of KNode (hi, Mathias).

BTW, I also commented out the saving to and loading from kpgprc of 
pgpUser as there is no longer a global PGP user id.

Regards,
Ingo
