You might have some success if you use the low level mechanism:
http://library.gnome.org/devel/gobject/stable/gobject-Signals.html#g-signal-handler-block
and/or
http://library.gnome.org/devel/gobject/stable/gobject-Signals.html#g-signal-handlers-block-matched
and/or
http://library.gnome.org/devel/gobject/stable/gobject-Signals.html#g-signal-stop-emission-by-name
etc. That's all at the individual signal level, but probably the
behaviour you're trying to block is in a signal handler somewhere.

A different tack would be to desensitize ("grey out") the Widget, ie
http://library.gnome.org/devel/gtk/2.12/GtkWidget.html#gtk-widget-set-sensitive
though that's probably not "stop UI updates" like you asked.
