The way I'm going is to avoid using autoconnect completely and
instead, manually connect the signals to the appropriate handlers, and
at that time, specify the right data. One way to make this process
simpler may be found in the source code for Devhelp, which uses a
function with a variable argument list to take a bunch of tuples of
widget names, signal names and functions to associate them to. Fixed
parameters provide the name of the glade file to use, as well as the
signal_data to pass to each signal handler.

You can then do something like this:

connect_signal_handlers("path/to/filename.glade", my_data,
 "my_button", "clicked", on_my_button_clicked,
 "your_button", "clicked", on_your_button_clicked,
 NULL);

Perhaps glade-3 has a better way of doing this?
