the generated program - not glade--.

That's because gcc 2.95 has a bug in it's dynamic_cast during the base 
ctor. And that's exactly the sort of code that glade-- generates.

Because gtkmm1 did not use dynamic_cast this is not an issue there. And 
because gcc 3.2 does not have the bug, gtkmm2 works with it.

Believe me: if you want to use gtkmm2 better upgrade your compiler now! 
If glade-- would work around the bug you might hit it in your part of 
the program real soon.

PS: if you have debian, I can give you advice on how to recompile 
libsigc-1.2 and libgtkmm2.0 .
