pinentry crashes on focus change

[David Given]

If pinentry if invoked with the -g option (which it always is), it will seg fault when the focus changes. Since I use focus-follows-mouse this means that just getting the mouse pointer to the pinentry window is kinda hard.

This looks very similar to this Red Hat bug from 2009:

The stack trace looks like this:
