By using g_signal_handler_disconnect() for example:
https://developer.gnome.org/gobject/unstable/gobject-Signals.html#g-signal-handler-disconnect

g_signal_connect() and related functions are returning the signal
handler it as a gulong, which you then can pass to
g_signal_handler_disconnect() and other functions working on signal
handlers.

Alternatively you can use g_signal_handlers_disconnect_by_func(), which
doesn't require you to store the signal handler it... but this is
slower.
