Cryptography: Key not selectable (PGP key)

[Tim Ruehsen <tim.ruehsen@gmx.de>]

Since a few weeks I can't select my PGP key for signing / encryption (thus 
signing and encryption do not work any more).

Basically the same problem in Kmail2 (Identities->Modify->Cryptography-
>Change) and in the Addressbook (Select Person, Crypto Settings, Change PGP 
encryption key).

When I select my key it starts to flicker (~1-2x per Seconds) and the OK 
button stays disabled. Within the address book I can work around it by 
selecting any other key (OK Button becomes enabled) and than selecting my key 
(OK Button stays enabled, flickering starts). Now the OK button works.

But in Kmail2 this work-around does not work since my key is the only one 
displayed.

I already looked at .gnupg/*.conf, but can't see anything obvious.

Any ideas ?
