Okay...  I just finished applying the patches.  I've by no means carried 
out any exhaustive testing but initial signs are that it's fixed the 
crashing issue.  I'll do some more comprehensive testing tomorrow but my 
first impression is that this stuff is still some way from working 
elegantly.  For example, Gtk::Widget::on_unrealize() is a virtual 
function.  However, if I override it in my derived class (MyDialog, 
which is derived from Gtk::Dialog), Gtk::Widget::on_unrealize() 
continues to get called, instead of MyDialog::on_unrealize().  
Unfortunately, I can't tell whether that problem already existed or 
whether the patches are somehow responsible.  To be fair though, that's 
the only issue I've noticed so I think we can definitely regard this as 
progress!

I've had a long and very tiring day today so I'll sign off for tonight - 
but if anyone can spare a few minutes, maybe they could try over-riding 
some of those on_xxx() functions (in their own, derived class) and see 
if the correct version gets called?  Many thanks to everyone for their help.
