[gtkmm] Uncaught exception: gtkmm-2.4 and win32

["Timothy M. Shead" <tshead k-3d com>]

Wondering if anyone else has run into this.  The enclosed test case 
attempts to load a non-existent icon using Gtk::IconTheme::load_icon().

Running on x86 Gentoo, gcc 3.3.4, no problem - it catches an exception 
of type Glib::Exception and exits normally.

Running on cygwin Win32, gcc 3.3.1 (cygming special), and using the 
excellent "gtkmm Developer Environment 2.4.5 for Mingw" from 
http://www.pcpm.ucl.ac.be/~gustin/win32_ports/, it does not catch any 
exception, and displays a dialog box "This application has requested the 
Runtime to terminate it in an unusual way" and terminates, despite the 
catch(...) block.

Anybody have any thoughts?

Cheers,
Tim Shead
