Ok.  I did manage to get something that seems to work ok by connecting 
to the button-release-event in the combo box's list.  The program 
doesn't crash any longer, and it loads the newly selected directory 
fine.  However it creates a message like this:
(gtkssh:23611): Gtk-CRITICAL **: file gtkwidget.c: line 5724 
(gtk_widget_is_ancestor): assertion `GTK_IS_WIDGET (widget)' failed

It doesn't seem to hurt the program any, but it looks bad so I'd like to 
fix the problem if I can.  Would anyone have any ideas?  The source code 
can be found here: http://cvs.kicken.mine.nu:8008/cvsweb.cgi/gtkssh/

Thanks again,
