当我尝试在 Ubnutu 上打开 KDE 应用程序时，我似乎遇到了一些 gtk 库问题。包括 Kate、Kile 等（打开 Mendeley 桌面时也发现了这个问题）
系统是64位的Ubuntu 12.04
附件是错误信息：
对于凯特来说：

对于 Mendeley：

/usr/bin/../../opt/mendeleydesktop/bin/mendeleydesktop: symbol lookup error: /usr/bin/../../opt/mendeleydesktop/bin/mendeleydesktop: undefined symbol: _ZN10QSslSocket16staticMetaObjectE
有什么解决办法吗？
