Description Zachary Dovel 2012-07-10 20:23:34 UTC 
Removing a menubar by passing NULL to gtk_application_set_menubar causes a segfault.  I have not tested this with the application menu.  According to the gtk documentation at <http://developer.gnome.org/gtk3/3.3/GtkApplication.html#gtk-application-set-menubar>,  this should be valid. I am currently using an empty GMenu to work around this bug.

STEPS TO REPRODUCE:

1. Create a GtkApplication
2. gtk_application_set_menubar (application, menu_model);
3. gtk_application_set_menubar (application, NULL);

BACKTRACE:

Program received signal SIGSEGV, Segmentation fault.
0xb78046d7 in g_menu_model_get_n_items () from /usr/lib/libgio-2.0.so.0
