关于（卸载）安装的奇怪消息

Question

很多时候当我（卸载）安装软件包时，我会收到奇怪的警告消息。这是一个片段：

Processing triggers for libglib2.0-0 ...
Processing triggers for man-db ...
Processing triggers for desktop-file-utils ...
Processing triggers for gnome-menus ...
Processing triggers for menu ...
Processing triggers for gconf2 ...

WARNING: node <gettext_domain> not understood below <schema>
WARNING: node <gettext_domain> not understood below <schema>
Processing triggers for hicolor-icon-theme ...
Processing triggers for shared-mime-info ...

有谁知道是什么原因造成的？这些看似无害的信息，但它们是什么意思呢？我该如何摆脱它们？

[更新] 运行sudo gconf-schemas --register-all没有帮助，并给我相同的警告消息。

[注意] 我使用 Debian Squeeze。
