Comment 1 Rolf Eike Beer 2014-08-17 08:51:34 UTC 
I have changed some bits of the decryption code, so this issue may already be fixed. Please try building a current version (4.14 or master branch). Instructions for building can be found here: http://utils.kde.org/projects/kgpg/building.php

Also I would like to know how you actually got to this point. Have you used the editor or did you right-click on a file in dolphin and selected decrypt there? Or something else?
Comment 2 J.D. 2014-08-18 22:50:48 UTC 
If I remember correctly I was in a terminal shell when this happened. I think I was downloading "mono-devil" when it occurred but it could of been right before.
Comment 3 Christoph Feck 2014-09-14 11:26:46 UTC 
Rolf, does comment #2 provide the requested information? Please set the bug status or add a comment.
Comment 4 Rolf Eike Beer 2014-09-14 11:34:34 UTC 
No, I needed the action that was done in KGpg, i.e. the place where "decrypt" was clicked.
Comment 5 Christoph Feck 2014-10-25 15:27:42 UTC 
If you can provide the information requested in comment #4, please add it.
Comment 6 Christoph Feck 2014-11-16 17:01:02 UTC 
To further investigate this issue, KDE developers need the information requested in comment #4. If you can provide it, or need help with finding that information, please add a comment.
Comment 7 Christoph Feck 2014-12-13 19:47:58 UTC 
No response, changing status. If you have more information, please add a comment.
