The g_error causes the abort.  This is probably because the function
name g_error does not indicate that this is fatal.  It would have been
much better if the gtk folks would have named this g_fatal or g_die.  I
stepped into this trap several times in the past.

Anyway I changed it so that the output will be

OK Your orders please

** (pinentry-gtk-2:20766): CRITICAL **: could not grab keyboard
ERR 83886179 canceled

It is actually intended that you can't use a password manager -
gpg-agent is the password manager!  If it would be possible to cut and
paste between windows other programs could do this as well; we try to
make this harder by grabbing the keyboard.  Put "no-grab" into
gpg-agent.conf if you don't like this feature.


Salam-Shalom,
