strange i18n problem

[Allin Cottrell <cottrell wfu edu>]

I'm just trying out a new de.po file for my program, running with 
LAND=de_DE (gtk 2.6.0, pango 1.8.0).  When I access the File menu, 
the program crashes.  This does not happen when running in any other 
language, and the po file looks OK.  It's difficult to get a good 
backtrace because it also freezes X, but here's what I got:

(gretl_x11:25193): Gtk-CRITICAL **:
gtk_widget_get_pango_context:
assertion `GTK_IS_WIDGET (widget)' failed

(gretl_x11:25193): Pango-CRITICAL **:
pango_context_get_language:
assertion `context != NULL' failed

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1229554944 (LWP 25193)]
0xb780b2a7 in
gtk_menu_item_expose (widget=0x8152730, event=0x824d338)
    at gtkmenuitem.c:737

The context in gtkmenuitem.c is the processing of a submenu:

context = gtk_widget_get_pango_context (GTK_BIN (menu_item)->child);
metrics = pango_context_get_metrics (context, GTK_WIDGET (GTK_BIN
                (menu_item)->child)->style->font_desc,
                 pango_context_get_language (context));

So it seems that (menu_item)->child is not a widget.

Any notions what might be happening here?  Thanks.
