No examples in documentation on using custom catalogues with gtkBuilder
I wanted to use the VteTerminal widget from the "Non-Gtk+ widgets and objects" menu, but gtk_builder_add_from_file failed with the error "vteTest.glade:18:1 Invalid object type 'VteTerminal'"
Much hunting around with google finally led me to "g_type_ensure(VTE_TYPE_TERMINAL);" as a solution, but I can't find any mention of this being necessary (or even that it is the correct solution) in any glade documentation. I realise it may be g_object and GtkBuilder issue, but it certainly caused me problems when using VteTerminal widget in a glade file.
