I can reproduce the problem.  After some head-scratching, I'm now pretty 
sure that this due to a problem in Glib that was uncovered by the 
introduction of Gtk2::InfoBar in Gtk2 1.230.

Gtk2::InfoBar also has a "response" signal, and just like Gtk2::Dialog, 
it installs a custom signal marshaller that converts the numeric 
response IDs to strings.  The problem is that Glib stores custom signal 
marshallers in a hash table keyed by signal names.  And since Gtk2 
1.230, Gtk2::Dialog and Gtk2::InfoBar both install a custom signal 
marshaller for the "response" signal on their respective type.  But 
since Glib just stores (signal name => signal marshaller) pairs, the 
entry for Gtk2::InfoBar replaces the entry for Gtk2::Dialog.  Glib needs 
to be fixed to store the associations in the form ((type, signal name) 
=> signal marshaller).

I don't think the current problem is directly related to this one, no.
