Hi,
I have similar problem, in my case it's caused by the fact that Kleoparta uses gpg instread of gpg2:
gbajson@misio:~/.kde/env$ gpg
gpg: /home/gbajson/.gnupg/gpg.conf:10: argument not expected
gpg: /home/gbajson/.gnupg/gpg.conf:11: invalid option
gbajson@misio:~/.kde/env$ gpg2
gpg: enabled debug flags: memstat
gpg: Go ahead and type your message ...
^C
gpg: signal Interrupt caught ... exiting
The following options are not supported by "gpg".
10 debug-level basic
11 log-file socket:///home/gbajson/.gnupg/log-socket
