calling cgnome_app_create_menus=>segfault in gnome_accelerators_sync ()

["sting sting" <zstingx hotmail com>]

Hello,
I have a little experience with gnomeui and I have a segmentation
fault iwhen creating a menu. This is the detailed description:
I  had written a small program (based on gnome-volume-control of Linux).
I have a segfaut ; backtracng in gdb gives
that the  segfault is in gnome_accelerators_sync () from 
/usr/lib/libgnomeui-2.so.0

I also see by printing that I reach the call to
	gnome_app_create_menus(GNOME_APP (app),main_menu);
but  do not reach
	printf("after gnome_app_create_menus \n");
(The full code is below).
Any idea o what  can be my mistake ?
