endless GtkWarnings within XUbuntu

[smarf]

Binary package hint: xfce4-terminal

After several tests, it seems that bug #651577 does not only affect meld or the small screen theme. Doing a clean install of XUbuntu 10.04 or 10.10, opening the xfce4-terminal and starting a program will result in Gtk-Warnings.

Starting meld (from the repository):
/usr/lib/meld/dirdiff.py:262: GtkWarning: gtk_label_set_ellipsize: assertion `GTK_IS_LABEL (label)' failed
  self.filter_menu_button.set_label_widget(label)
/usr/lib/meld/dirdiff.py:262: GtkWarning: gtk_label_set_angle: assertion `GTK_IS_LABEL (label)' failed
  self.filter_menu_button.set_label_widget(label)

Starting synaptic (from the repository) or truecrypt (from the original binary):
Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkOptionMenu::indicator-size' of type `GtkRequisition' from rc file value "0" of type `glong'
Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkOptionMenu::indicator-spacing' of type `GtkBorder' from rc file value "0" of type `glong'
