Comment 17 for bug 371178

unfortunately, I have put my observations in the wrong thread! Sorry for that. The problem with pinentry-qt4 (input dialog window foe entering passphrase) still persists. Using Kmail alone is fine as long as I use pinentry-gtk-2 for Encryption, Signing or Decryption (of course with gpg-agent.conf setup to include the statements supplied above. The complete system break-down occurs as soon as kleoptatra is installed (its "use-agent" dependency is fixed and points to pinentry-qt4). No amount of configuration tuning helps to get the pinentry-qt4 input window to come to fore and accept any meaningful entry. The work-around to replace pinentry-qt4 with pinentry-gtk-2 fails too. As a result no encryption or decryption is possible with kleopatra installed together with kmail. I had to remove the package kleopatra to get the kmail up and running again with pinentry-gtk-2.

Kubuntu 11.04 (all updates till date installed)
KMail Version 1.13.6
under KDE Plattform-Version 4.6.2 (4.6.2)
