tooltips bug causes segfault.

[Todd Dukes <tdukes ibmoto com>]

The simplified format of my window is like this

------------------------------
|                             |
|  clist                      |
|                             |
-------------------------------
 ------   -------   -------
|entry | | entry | | entry |
 ------   -------   -------

The clist has a pop-up menu. One of the options
is close. When close is selected, the window and
all of the widgets inside it are destroyed.

The entry fields each have a tooltip.

If the pop-up menu is positioned so that the close
item is over one of the entries, my application my
segfault. The stack track looks like it is processing
a tooltip widget. The last few functions in the stack 
trace are:

gtk_tooltips_event_handler ()
gtk_tooltips_set_active_widget ()
gtk_widget_hide ()

What I believe is happening is that a signal is emitted to
tell the tooltip to display itself is emittedm but by the time
it gets to the widget, the widget isn't there any more.

Would this be considered a bug in my code or a bug in the toolkit?

I am using gtkmm and haven't isolated whether this is gtkmm only or
not.

thanks,
Todd.
