是不是文件链接丢失了，建议重新安装一次 python。
如果你其它程序也有类似问题，可能还需要重装系统。

[kaelsunkiller]

【已解决】

重装了python2也无效，但从调试结果看应该还是python相关的动态链接库问题；
解决办法：
重装所有依赖包以及依赖包本身的依赖
wiki提及的依赖包：https://github.com/XX-net/XX-Net/wiki/How-to-use

ubuntu 下，可能需要安装
- sudo apt-get install python-openssl
- sudo apt-get install libffi-dev
- sudo apt-get install python-gtk2
- sudo apt-get install python-appindicator
- sudo apt-get install libnss3-tools

同时使用apt-cache查看这些包的依赖包
apt-cache depends *your-package*
如：

python-gtk2
Depends: python
Depends: python
Depends: python:any
python:i386
python
Depends: libatk1.0-0
Depends: libc6
Depends: libcairo2
Depends: libgdk-pixbuf2.0-0
Depends: libglib2.0-0
Depends: libgtk2.0-0
Depends: libpango-1.0-0
Depends: libpangocairo-1.0-0
Depends: python-cairo
Depends: python-gobject-2
Breaks: python-gtkglext1
Suggests: python-gtk2-doc

Depends全部重装
sudo apt-get install --reinstall *your-package*
之前还瞎操作了好多步骤，不知是否相关，包括重装很多其它的系统依赖包（因为系统一些其他软件也出现不同的错误），重装miredo等；
差点就重装系统了。。。太难了

[SeaHOH]

所谓重装肯定不是单指本体啦。
其实我觉得吧，还重装下系统的好，因为你都不清楚自己到底破坏了哪些组件，记得要先各种备份。
