------- Comment #1 from Murray Cumming  2008-03-07 12:13 UTC -------
Thanks for the bug report. I have added this and another new function:

2008-03-07  Murray Cumming  <murrayc murrayc com>

        * libpanelapplet/src/libpanelapplet_methods.defs: Regenerated with 
        h2defs.py (in pygtk).
        * libpanelapplet/src/applet.hg: Added request_focus() and 
        set_background_widget().
        Bug #519340 (Fanosek).


And I have just made a 2.22 tarball release. If you can't depend on that, you
can use gobj() and Glib::wrap() to use the C API with the C++ object.

Actually, I am surprised that anyone is really using this, but I am happy if it
is useful.

------- Comment #2 from Murray Cumming  2008-03-08 21:58 UTC -------
Fixed. This warning was only shown when we really didn't want to do anything,
so it was harmless:

2008-03-08  Murray Cumming  <murrayc murrayc com>

        * gtk/src/container.ccg: remove_callback(): When just calling the C 
        callback, because the C++ object has already been destroyed, don't 
        even call the C callback if the GType is exactly GtkContainer. This 
        avoids a useless warning from GTK+ about an unimplemented remove() 
        default signal handler. This happens when deriving from Gtk::Container
- 
        remove() really is implemented - it's just that we don't call our own 
        implementation when that would be impossible.
        Bug #518002 (Jonathon Jongsma).

           Summary: Impossible to catch ConvertError exception
           Product: glibmm
           Version: 2.15.x
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: general
        AssignedTo: gtkmm-forge lists sourceforge net
        ReportedBy: jonathon quotidian org
         QAContact: gtkmm-forge lists sourceforge net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


When using Glib::Markup::Parser to parse a GMarkup document, if it encounters
invalid UTF-8, it throws an exception which seemingly can't be caught.  I don't
understand why, but I can't seem to catch it.  Test case attached.

Created an attachment (id=106878)
 --> (http://bugzilla.gnome.org/attachment.cgi?id=106878&action=view)
test case illustrating the uncatchable exception.

When I run the attached program, I get the following output, even though I'm
attempting to catch instances of Glib::MarkupError, Glib::ConvertError, and
Glib::Error:

Glib::MarkupError: terminate called after throwing an instance of
'Glib::ConvertError'
Aborted (core dumped)

Yes, I get that too, and I can't understand why. Here is a slightly changed
