关键错误:在加载我的xfce插件时，没有足够的参数传递给包装器。

Question

我编写了一个非常简单的xfce面板插件片段：

#include <gtk/gtk.h>
#include <libxfce4panel/xfce-panel-plugin.h>

static void system_monitor_construct(XfcePanelPlugin *plugin);

XFCE_PANEL_PLUGIN_REGISTER(system_monitor_construct);

static void system_monitor_construct(XfcePanelPlugin *plugin)
{
    GtkWidget *hvbox;
    GtkWidget *label;
    GtkOrientation  orientation;

    orientation = xfce_panel_plugin_get_orientation (plugin);
    hvbox = xfce_hvbox_new (orientation, FALSE, 2);
    gtk_widget_show(hvbox);

    gtk_container_add (GTK_CONTAINER (plugin), hvbox);

    label = gtk_label_new ("Hello GNOME!");
    gtk_container_add (GTK_CONTAINER (hvbox), GTK_WIDGET (label));
    gtk_widget_show(label);

}

它是用下列内容汇编的：

gcc -Wall -shared -o libtest.so -fPIC main.c `pkg-config --cflags --libs libxfce4panel-1.0` `pkg-config --cflags --libs gtk+-2.0`

将libtest.so复制到/usr/lib/xfce4/panel-plugins，并在/usr/share/xfce4/panel-plugins中创建桌面文件test.desktop，内容如下：

[Xfce Panel]
Type=X-XFCE-PanelPlugin
Encoding=UTF-8
Name=test
X-XFCE-Module=test
X-XFCE-Module-Path=/usr/lib/xfce4/panel-plugins

当我加载这个插件时，我得到：

(process:5700): xfce4-panel-wrapper-CRITICAL **: Not enough arguments are passed to the wrapper
xfce4-panel(external): test-8: child exited with status 512

(xfce4-panel:5695): xfce4-panel-WARNING **: Plugin test-8 exited with status 2, removing from panel configuration

(xfce4-panel:5695): exo-CRITICAL **: IA__exo_gtk_object_destroy_later: assertion 'GTK_IS_OBJECT (object)' failed

我哪里错了？或者我错过了什么？

试着尝试..。此问题是由于Comment条目丢失在桌面文件中引起的。
