Thanks again for your help.  The problem seems to be with pinentry when gpg is 
invoked manually:

gpg: problem with the agent: No pinentry

and then as a consequence:

gpg: public key decryption failed: General error
gpg: decryption failed: No secret key

However, I have remerged pinentry.  :-(

Initially, I thought this was related to updating media-libs/jpeg-8 and 
library libjpeg.so.7, but it seems that it may be related to qt3 becoming 
deprecated?  Perhaps I should unmask app-crypt/pinentry-0.7.6 which has qt4 in 
its USE flags and try with that?

Meanwhile I just resync'ed and there's a load of kde-4.3.5 updates.  Perhaps I 
was cought up in some major update bonanza and that's why this broke.  I'll 
finish the update and see how it goes.
