Do you run this using a plasma desktop or a GTK based one? The error message you reported

   "Gtk-Message: 19:50:38.861: GtkDialog mapped without a transient
   parent. This is discouraged."

leads me to ask this question. From the symptoms it seems, that the gpg-agent is not able to ask for the passphrase. Using gpg seems to work perfectly because you can encrypt files (which does not need an UI interaction).

When you decrypt manually, do you enter your passphrase in the console window or does a separate window popup and asks for the passphrase?

By all means: this is not a KMyMoney issue but somehow caused by surrounding technology. What is the output of the following command (I believe Fedora is an RPM based distro):

   % rpm -qa | grep pinentry

Regards

Thomas
