It looks like you found a real problem. Thanks:
http://lists.gnome.org/archives/gnome-vfs-list/2004-July/msg00009.html

For now, I have appplied the patch with these changes:

1. I added comments next to every new and every delete.

2. I think that the callback given to gnome_vfs_async_find_directory will only
be called once, so we can delete the proxy there.
http://developer.gnome.org/doc/API/2.0/gnome-vfs-2.0/gnome-vfs-20-gnome-vfs-async-ops.html#gnome-vfs-async-find-directory

3. I added g_warnings where there are leaks, so that people can decide not to
use them. I think that is just Handle::transfer() and Handle::cancel().

I have attached the revised patch so you can see what I did. Please look it over
and test the changes, because I am not using these methods. In fact, it would be
great if you could add an example that uses them.

Please make a cvs patch if you need to patch it again:
http://www.gtkmm.org/bugs.shtml#CreatingPatches

Thanks again.

I can't reproduce the crash on debian testing, either with my built-from-source
gtkmm, or with the libsigc++ 2.0.3 and gtkmm 2.4.2 debian packages that are in
testing.

I have tried clicking on the button and pressing keys. I guess it crashes for
you whe you press a key. Valgrind also did not show anything interesting.

Did you build libsigc++, glibmm, and gtkmm from source, or are you using the
debian packages.

If you built them from source, did you rebuild glibmm and gtkmm after you
updated libsigc++? (an earlier version of libsigc++ 2.0.x was very broken) 

Or, can you tell us more about your architecture? Is this a regular x86 PC?

a) The bug report makes no sense.
b) There was no response.

------- Additional Comments From murrayc murrayc com  2004-07-08 12:24 -------
I have added this text to the libglademm chapter:
<para><literal>get_widget()</literal> returns child widgets that are manage()ed
(see the <link linkend="sec-Memory>Memory Management</link> chapter), so they
will be deleted when their parent container is deleted. So, if you get only a
child widget from libglademm, instead of a whole window, then you must either
put it in a Container or delete it.
Windows (such as Dialogs) can not be managed because they have no parent
container, so you must delete them at some point.</para>

That should take care of that. I leave the other point to you, as suggested.

I'm using the Debian unstable packages on a Pentium III. The crash occurs if you
start the program and press enter a couple of times (say four or five).
