请求 QGIS 2.2 访问台式机上的数据时发生崩溃。运行 Ubuntu 14.04 LTS。
通过终端以 root 身份运行 QGIS 桌面确实允许我打开文件！但程序运行后（即初始加载/欢迎图形消失后）也会立即弹出错误消息：
图层 /usr/share/applications/%F 不是有效图层，无法添加到地图中
有什么想法可以让我让 QGIS 以 root 权限从 GUI（unity）运行，而无需通过终端打开它并添加 sudo 前缀？
我已尝试 edm 在下面提供的解决方案，但打开的窗口挂起，并且我收到与 klauncher 相关的错误：无法启动进程无法与 klauncher 对话：未连接到 D-Bus 服务器。如何从 Unity Launcher 以 root 身份启动应用程序？
可能是我的 KDE 配置文件已损坏。有什么办法可以纠正这个问题，以便我可以从 unity 运行 qgis？
我对此还只是个初学者，因此如果我需要发布更多命令输出，请提供任何说明。
$ qgis

任何请求，例如打开文件、浏览、创建新项目等都会导致崩溃。

以 root 身份（通过终端）运行程序可以正常工作。但是出现了一个新错误：
