Problem with pinentry-0.6.7

[Matthias Welwarsky]

Hi,

just updated to a more recent version of gpgme/cryptplug, now I'm facing a 
nasty problem. Using the openpgp-cryptplug in kmail, I cannot sign/encrypt 
messages any more. The plugin always returns "Error #19 no passphrase". I 
straced the gpg-agent and found that it forks into pinentry-qt, but the 
pinentry-qt is then unable to connect to the X server for some reason. So, 
the pinentry fails, resulting in the error mentioned above. Any idea what I 
can do to restore the functionality?

kind regards,
