[Bug-gnubg] Empty dialog when requesting hint on a resignation

[Russ Allbery]

Steps to reproduce in 1.02.000:

1. Start a new match
2. Resign after a few moves
3. Select (in the GUI) the previous game to see the history
4. Select the resignation move
5. Press Ctrl-H for a hint

gnubg pops up a dialog box that's empty except for an info icon and the
Close button and displays the following error:

(gnubg:1146): Gtk-CRITICAL **: IA__gtk_container_add: assertion `GTK_IS_WIDGET 
(widget)' failed

This is an improvement over the 1.01.003 behavior, where gnubg would die
with the following assertion error:

ERROR:gtkcube.c:980:CreateCubeAnalysis: code should not be reached
Aborted (core dumped)

That part seems to be fixed in 1.02.000, but there still seems to be
something amiss.
