Did you read the documentation for gtk_builder_connect_signals(), and 
follow the advice about compiling and linking against 
gmodule-export-2.0?

http://library.gnome.org/devel/gtk/unstable/GtkBuilder.html#gtk-builder-connect-signals

For instance, if you are using pkg-config, add gmodule-export-2.0 to 
your PKG_CHECK_MODULES call:

PKG_CHECK_MODULES([DEPS], [gtk+-3.0 gmodule-export-2.0])

Note that if you are building your application for Windows, you must add 
G_MODULE_EXPORT to the declaration of signal callbacks. As this is a 
no-op on Linux and other Unices, it is good practice to declare every 
signal callback like this, even if you only plan to build for Linux.

GtkBuilder has been in GTK+ 2 since 2.12, so I do not think that this is 
a new problem.
