I don't exactly know what are you doing or using, but there is one
possibilty - you are using Glade to create GUI and save a result in
GtkBuilder .xml format (which is now a default), which is probably
incompatible with libglade .xml format and now you are trying to load
GtkBuilder using libglade. See one of two solutions:
1. Continue using libglade, but edit your glade .xml file in Glade and
try to save it in Glade format.
2. Switch from libglade to GtkBuilder - libglade is deprecated anyway.
GtkBuilder is wrapped in gtkmm.
