How to rethrow exception or install exception handlers inside Gtk::Main::run

[Germán Diago <germandiago gmail com>]

Hi all. I'm implementing a program with gtkmm and I found that when 
throwing an exception from
inside Gtk::Main::run (an exception from my program logic), I can't 
catch that exception from my main() function since Glib catches the
exception (I think) and rethrows a Glib::Exception. This way I loose the 
information from my exceptions. Is there any workaround to be able to 
get my original
exception outside of the main loop? Thank you.
