我在 OpenSuse 42.1 Leap OS 中使用 KDE 时遇到了问题。基本上，所有需要 Qt 的东西都无法运行（kate、Libreoffice、dolphin 等）。
当我单击图标的应用程序时，我收到一条错误消息。通常是这样的：“KDEInit 无法启动‘/usr/bin/kate”ls 但有时也会这样：“错误 - Plasma：内部错误。请将完整的错误报告发送至http://bugs.kde.org. 统计中出现未知错误情况：没有到主机的路由”
在启动时我通常会收到以下消息：“很抱歉，Init5 意外关闭。您无法报告此错误，因为 kdeinit5 没有提供错误报告地址。”“详细信息：可执行文件：kdeinit5 PID：1866 信号：分段错误（11）时间...”完整的崩溃消息是线程末尾引用的消息。
我有另一台电脑，上面安装了相同的操作系统，配置也相同。这两个系统以前都运行良好。现在报告此消息的系统可能已被其他人修改过。在这两台电脑上，我都在 /opt 中安装了 Qt5.5.0。我记得如果在 /etc/ld.so.conf 中设置了 /opt/Qt5.5.0/..lib 路径，但文件中没有提到 qt，就会出现问题。
一些其他信息（两个系统）：
Kernel version: linux-e5re 4.1.12-1-default
linux-e5re:~ # qmake --version
QMake version 2.01a
Using Qt version 4.8.6 in /usr/lib64
我遇到了一些与此类似的问题，并使用以下方法解决了这些问题：
go in /opt/Qt5.5.0/5.5/gcc_64/bin
mv qdbus qdbus-qt5
我已经检查过 /usr/bin，其中有 qdbus 和 qdbus-qt5
到目前为止，我在其他论坛上读到的资料都没有用。
有什么建议吗？
谢谢
