Pygtk 状态图标无法加载？

Question

我现在正在写一个小脚本，需要用到 gtk.StatusIcon()。但不知道为什么，它的表现有点奇怪。如果我在 Python 的交互式命令行里输入：

>> import gtk
>> statusIcon = gtk.status_icon_new_from_file("img/lin_idle.png")

Pygtk 正常工作，会在系统托盘里显示一个图标（lin_idle.png）：

这工作得很好

但是，如果我在我的脚本里尝试做同样的事情：

def gtkInit(self):
    self.statusIcon = gtk.status_icon_new_from_file("img/lin_idle.png")

当调用 gtkInit() 时，我看到的是这个：

我在和交互式 Python 命令行相同的工作目录下运行脚本，所以我很确定它能找到这个图像，但我还是搞不懂... 有人有什么想法吗？谢谢大家。

更新：不知道为什么，在脚本里调用 gtk.status_icon_new_from_file() 几次后，它最终会创建图标，但这个问题依然存在。不知道有没有人能帮我找出问题出在哪里？

应要求：这是完整的脚本。其实这是我正在早期阶段制作的一个应用程序，但如果你设置正确，它现在是可以工作的，所以如果你想的话可以随便试试（也可以帮我！），你只需要获取一个 imgur 开发者密钥，并把它放在 linup_control.py 里。
